#Etching method is a chemical processing method
Text
1、 Cutting method
Cutting method is currently one of the most widely used thread machining methods. This method can use cutting tools such as turning tools, cutting cutters, and milling cutters for machining. The cutting method is simple to operate, but requires precise machining equipment and low machining efficiency. In addition, due to the slow relative movement speed of the cutting tool, it may cause the problem of rough machining surface.
2、 Etching method
Etching method is a chemical processing method, which has the advantage of being able to process very small and complex thread shapes. The etching method requires the use of chemicals such as acids and bases for processing, and requires hazardous material management and strict operating procedures. In addition, the etching method also requires the processing of molds, so the cost is relatively high.
3、 Rolling method
Rolling method is a processing method that uses rollers to press the workpiece and convert its shape. Rolling can process the surface of a workpiece into parallel and continuous external and internal threads. Compared to the cutting method, the rolling method has the advantages of high machining efficiency, good surface quality, and high material utilization of workpieces, especially suitable for large-scale thread processing.
4、 Line cutting method
The wire cutting method is a method of using high current discharge to process the spiral shape on the electrode along the workpiece. This processing method can produce very small spiral lines, with high processing accuracy and good surface quality. However, the processing speed of wire cutting method is relatively slow, and it also requires periodic maintenance and upkeep of the processing equipment.

Milestone Monday
On this day, November 6, 1771, Alois Senefelder (1771-1834) inventor of lithography was born. The son of an actor and tasked with supporting his mother and siblings after his father’s death, Senefelder began his own acting career at age twenty and extended his occupational talents into playwriting. Unable to afford to publish a new play he’d written, Senefelder experimented with what he called “stone printing” in the 1790s, etching acid resistant ink onto limestone and subsequently inventing the first planographic process in printing. Senefelder perfected the chemical process and designed a special printing press with the help of the André family and within five years lithography was being used as a cheap form of creating reproductions by publishers and in mapmaking by land surveying offices throughout Europe.
By the early 1800’s Senefelder and his contemporaries were thinking of ways to introduce color to lithography. Senefelder outlined his ideas on chromolithography in his 1818 book A Complete Course of Lithography, but it was Godefroy Engelmann of France who was awarded the patent for it in 1837.
In celebration of Senefelder’s birthday and all that he contributed to the printing world; we’re looking at the American Encyclopedia of Printing published in 1871 by Menamin & Ringwalt of Philadelphia. Included within the section on lithography is a storied portrait of Senefelder surrounded by his tools and accomplishments. The lithographic portrait was printed by Duval & Hunter, lithographers and chromo publishers out of Philadelphia.
It wasn’t long before artists saw the appeal of lithographs and began taking advantage of the new printing technique. Lithography was far more approachable than other printing methods of the time like engraving, because artists could draw directly on the stone with familiar tools, such as pens and crayons. They did not need to master a new medium or skill to create highly accurate prints with deep textural qualities.
Among the artists of the 1800’s diving into lithography, Honoré-Victorin Daumier (1808-1879) excelled in the medium. Daumier was a prolific French artist who created more than 4,000 lithographs in addition to his many sculptures, paintings, drawings, and wood engravings. His specialty was satirical social caricatures of Parisian life where he effortlessly blended artistry, social commentary, and humor as showcased in the following lithographs held within our collection. The prints were published in 1840 by La maison Aubert of Paris.

hey, quick question because i'm not sure what to search online to find it and iirc you did/do metalworking etc so i thought i'd ask: what's the term for when you emboss metal but then darken the surroundings so the embossed designs contrast/'pop' more?
I'm not sure there's one particular term for the two processes you're describing, but I could be wrong! 'Patination/patinating' is the word that comes to mind: the creation of an oxide layer on the metal to create a different colour. It's only surface deep, and can usually be polished or sanded off, depending on how thick the layer is. It's a separate process from embossing.
Embossing (chasing and repoussé) is pretty much just the moving of metal into a raised pattern or relief, and you can either bring out the details with an oxidising fluid/antiquing fluid or leave it as it is. Metals are usually oxidised with acids to produce a darker surface finish, which is often then polished away from the high points to create contrast. With silver or copper (though not brass), you generally use liver of sulphur, and with ferrous metals often a selenious acid is used in commercial 'antiquing fluids', but there are a number of others that work. You can also use heat to produce different oxides and colours on the surface, but you have to be careful about affecting the temper/hardness of steel, and know that any other metals or materials will be affected differently with heat.
This is an interesting article from the Met about techniques of metalwork decoration.
Other methods related to this are: gilding, damascening (mechanical rather than chemical application of a softer metal (gold) to a harder one (steel)), blueing (chemical or hot, but it's still a patina, specifically for ferrous), chemical etching (vs mechanical engraving).
This amazing 16th century armour from the Wallace Collection has all of the above:
I'm not sure I've really answered your question, so feel free to drop back with more if I can help any further!

Liquid cell transmission electron microscopy analysis of semiconductor nanocrystals
Semiconductor nanocrystals of different sizes and shapes can govern the optical and electrical properties of materials. Liquid cell transmission electron microscopy (LCTEM) is an emerging method to observe nanoscale chemical transformations and inform the precise synthesis of nanostructures with expected structural features. Researchers are investigating the reactions of semiconductor nanocrystals with the method to study the highly reactive environment produced via liquid radiolysis during the process.
In a new report now published in Science Advances, Cheng Yan and a research team in Chemistry and Materials Science at the University of California Berkeley, and the Leibniz Institute of Surface Engineering, Germany, harnessed the radiolysis process to replace the single particle etching trajectory of prototypical semiconductor nanomaterials. Lead selenide nanotubes used during the work represented an isotropic structure to retain the cubic shape for etching through a layer-by-layer mechanism. The anisotropic arrow-shaped cadmium selenide nanorods maintained polar facets with cadmium or selenium atoms. The trajectories of transmission liquid cell electron microscopy revealed how the reactivity of specific facets in liquid environments governed the nanoscale shape transformations of semiconductors.

Factors That Affect the Cost of Engraving and chemical etching
Engraving and chemical etching are techniques used to create designs or patterns on various materials, including metal, glass, and plastic. Engraving involves using a tool or machine to physically cut or remove material from the object's surface, creating a recessed or raised design. On the other hand, chemical etching uses a chemical solution to dissolve or etch away the material. You can recess into the surface by creating a layout. Both techniques create intricate designs and patterns.
However, the cost of these processes can vary greatly depending on several factors. This post will examine several essential elements that impact engraving and chemical etching costs.
Type of Material
One critical element affecting these operations' price is the type of metal being etched or engraved. Some metals, such as stainless steel, are more expensive than others. This will be reflected in the price of the final product. Additionally, the thickness of the metal can also affect the cost, as thicker materials may require more time and resources to etch or engrave.
Design Complexity
The complexity of the design is another factor that can affect the cost of engraving and chemical etching. More complex procedures like custom signs may require more time and resources to produce. Also, designs requiring multiple colours or layers may affect the price.
Customization
Customization is another factor that can affect the cost of engraving and chemical etching. Suppose a customer requests modifications or changes to the design or engraved sign. These requests can add additional time and resources to the process. Additionally, if a customer requests unique things like custom signs or special materials, this can also affect the cost of the process.
Quantity
The quantity of parts produced is another factor affecting the cost of engraving and chemical etching. Due to economies of scale, the cost per part will usually decrease as the quantity increases. However, it's important to remember that extremely large quantities may require additional resources and setup time which can increase the final cost.
Additional Services:
Additional services can also affect the cost of engraving or etching. For example, if you require different finishing or polishing on the engraved signs or etched pieces, this can add to the price. Similarly, if you need to ship the item to a specific location, this can also add to the cost.
Many companies provide chemical etching services for the production of high-precision metal parts. With over two decades of expertise, they are known for producing delicate and intricate details as fine as 0.35mm.
How to find the correct service provider:
Research different chemical etching companies: Look for companies with experience in the type of etching you require. Check for customer reviews to gauge their reliability and quality of work.
Consider the service provider's capabilities: Confirm that the company can produce parts with the level of precision and complexity that you require.
Assess the lead time and cost: Many companies provide cheap engraving services. Compare different providers' lead time and cost to ensure you get a cost-effective and timely service.
Check for additional services: Find out if the company offers other services, such as multi-colour fills, to ensure that you have a one-stop shop for all your etching needs.
Please communicate with the service provider: Reach out to the company and ask any questions to ensure they are the right fit for your project.
Final Thoughts
Several factors can affect the cost of engraving and chemical etching. Many service providers provide cheap engraving services, but it is essential to remember that the most affordable option may only sometimes offer the best quality or meet your specific needs.
However, chemical etching and engraving are cost-effective and efficient methods of producing high-quality and precise metal parts despite these factors.

WHAT IS BETTER 18K OR 24K FOR GOLD PLATING JEWELRY DESIGN?
To gold plate something, you put a tiny layer of gold on top of a base metal. Making a lot of different kinds of gold-plated jewelry design involves this step.
The jewelry can really look like solid gold. This type of jewelry design, on the other hand, is much less expensive. Because of this, gold finishing is very common for both cheap and expensive jewelry.
There are differences in how thick and good the gold covering is. Because of this, you need to know about gold covering before you buy. On top of that, gold layering does fade over time. So, you need to take good care of gold jewelry design to make sure it lasts a long time. So be careful, especially if you use it more often. In general, though, gold finishing is an excellent method to get the fancy look of gold by not spending a lot of money.
WHAT 18K AND 24-K GOLD PLATING MEAN?
To comprehend how gold stacking works, you need to know a few things about gold. Karats (k) are a way to measure gold. 24k is the purest form of gold. To make jewelry design, though, pure gold tends to be soft. People often blend it with metallic substances to make it stronger. This is where 18k gold plating as well as 24k gold plating vary.
75% of 18-k gold is pure gold as well as 25% is different metals. The 24-k gold lining, on the other hand, is a coat of real gold. Electroplating on an initial metal made it possible for it to exist. It is more sturdy and more resistant to discolor than 24-k gold, but 24-k gold plating looks more expensive and rich. Which type of gold plating to use relies on the jewelry design’s style and purpose.
18-K and 24-K gold plating are mixed together
When it comes to gold layering from Indian jewelry online, most people use two designs. Some of them are 18-karat and 24-karat. The amount of gold within each is the main difference among them. 24-karat gold enamel is 100% pure gold, while 18-karat gold enamel has 75% gold in it. Electroplating, also a thin layer of gold into a base metal is what it does. That’s why both kinds of gold enamel utilize either etching or electroless treatment.
When you electroplate, you run an electric current with a solution that has gold ions in it. Electroless layering, on the other hand, uses a chemical process. An artificial mix of gold ions as well as the metal are reacting without electricity. Both ways result in effective, even, deep plating that gives different finishes for different uses.
18-K and 24-K gold plating are not all the same color
You can tell the distinction in color between 18-k and 24-k gold finishing in Indian jewelry online, particularly when it comes to rose and white gold. When making 18-karat gold, though, people often mix it with different metals like copper, silver, and zinc. Because of this, the gold looks more yellow rather than as vibrant as 24-k gold. On another hand, 24-k gold is pure gold. The procedure also changes the metal’s surface, leaving it more malleable and simple to scratch while also making it look lighter.
The best way to get a rose gold polish is to use 18-k gold treatment. Because it has copper in it, 18-k has a red color. For a white gold look, though, 24-k gold works best because it has a tone more like silver. In the end, the choice within 18-k and 24-k gold finishing comes down to your own preferences and how you want your jewelry to look.
18-K and 24-K gold plating cost different amounts
It is important to know the difference between 18-k and 24-k gold if you are thinking about gold plating. Gold that is 18-k is 75% gold and 25% additional metals. Gold that is 24-k is 99.9% gold. It indicates that 24-k gold enamel costs more and has greater amounts of gold in it than 18-k gold plating. The disparity in cost among the two can be very big or very small, based on the project. A 24-karat gold covering is still usually a high-end choice for things like jewelry or high-end electronics.
You could opt for 18-k gold layers, though, if you want something that will be useful a lot of the time. It lasts longer and doesn’t fade as easily. Before you choose one of these choices, you should know what you need to know regarding gold and the way it affects the price difference between plating types.
How long 18-K and 24-K gold plating lasts and how well it wears?
When it comes to gold plating, longevity and durability are very important things to think about. For instance, 18-k and 24-k gold-plated items last longer and are more durable than lower-karat choices. You can choose between 14k gold or 10k gold. But even this much gold plating may rub off over time, mostly if it is not treated properly. You should keep gold-plated jewelry away from strong chemicals or rough surfaces because of this. Also, don’t wear it when you swim or take a shower.
Polishing and cleaning gold-plated jewelry on a regular basis will also keep it looking good and make it last longer. The gold finish will wear off over time, though, even with good care, showing the base metal below. If you want 18-k or 24-k gold plating to last longer, you need to take good care of it and keep it in good shape.
Normal uses for 18-K and 24-K gold plating
Gold is a popular metal for Indian jewelry online makers because it is smooth and simple to scratch or damage. Jewelry often uses 18 karat (18k) gold finishing, which is 75% pure gold. It’s a good mix of longevity and value for money. Such a good material for everyday use makes it perfect for engagement rings, bracelets, as well as chains.
24k gold plating, contrary to popular belief, is made of 99.9% pure gold as well as the best gold which can be used to make jewelry. It makes the jewelry piece look more expensive and shiny. Luxury items like watches, buttons, and earrings often use 24 karat gold. However, because it is soft, there are choices that last longer, and it needs more care to keep its shine.
People often put 18-k enamel on Indian jewelry online, gadgets, and car parts to make them look nice. People use 24-k metal for both surgical posts and high-end expensive items at the same time. Both types of enamel are useful in their own ways, but 24-k gold plating is usually more expensive. It’s because there is a lot of pure gold in it. Even so, 18-k is still popular because it lasts a long time and can look like more expensive things.
Conclusion
This change in purity in jewelry means that the price is also different. For instance, pure 24k gold costs more than 18k gold because it has more gold in it. Gold plating is a good idea because it makes the thing more valuable and lasts longer. What makes the cost distinct among them both in the end relies on two things. They say how big the thing is that needs coating and how much gold it needs. Because of this, it is important to talk to a professional you can trust before choosing which gold plating plan to go with.

Laser Engraving And Laser Marking Similar Or Different Processes?
Laser etching, marking, and engraving are the most versatile modern inventions that are used in almost every industrial sector. While the difference between the laser engraving and laser marking and laser etching is quite evident, the terms laser marking and engraving are confused at times. Laser marking, is a method that leaves markings on a surface material of an object, including colour change, owing to chemical alteration.
Laser engraving is the method that is carried out by inscribing on an object surface. Laser engraving does not involve any inks or dyes, so it gains an advantage over the laser marking, wherein the replacement of tool bits like the ink heads need not be done. Laser marking has its own pros like the preservation of surface without any impact on it, since it uses colours and dyes to mark on the material surface thorough the laser techniques. Laser-sensitive polymers, metal alloys play an important role in this method. The method in general is a generic term that encompasses a variety of surfacing marking techniques like printing, hot-branding, laser attachment and so on.
On the other hand Laser engraving selectively removes minute layers of the surface material creating visibly conspicuous marks which are permanent. Different material surfaces respond to the laser in different ways. Harder surfaces primarily are responsive to ablation where the laser beam dislodges the minute particles from the surface. Engraver can create deep incisions, whereas laser marking is usually much shallower comparatively. Very short bursts of precise laser pulses or beams are done to get a clear marking, as transmit large quantity of power even without high degree of heating or melting the material surface.
Laser engraving is a part or a subsection of laser marking but however since it differs in quite a few ways it is separated from the laser marking. Mainly there are three types or categories in laser engraving, Laser ablation, deep laser engraving and laser etching. The difference in these three is the amount or the depth of engraving that is carried out depending on the requirement and the nature of the material surface. Laser ablation is the quickest way to mark on a material surface. This method is most suitable for engraving on parts that are subjected to high wear, marking serial numbers; logos, engine and chassis number engraving and so on. In laser etching, engraving is carried by the heat caused by the beam on to the surface of the material.
Nevertheless machines that are used for laser engraving and laser marking are almost similar, by virtue of the technology. But in a lot of cases these terms are confused due to the lack of awareness. Organizations like Signvec are pioneers in supply and service of laser marking machine and laser engraving machines. Located in Singapore the company has carved out a solid place for itself in the mentioned sector and has been maintaining a solid clientele, with reputed names included in it.

A new world of 2D material is opening up - Technology Org
New Post has been published on https://thedigitalinsider.com/a-new-world-of-2d-material-is-opening-up-technology-org/
A new world of 2D material is opening up - Technology Org
Materials that are incredibly thin, only a few atoms thick, exhibit unique properties that make them appealing for energy storage, catalysis and water purification. Researchers at Linköping University have now developed a method that enables the synthesis of hundreds of new 2D materials. Their study has been published in the journal Science.
In a film that measures only a single millimetre, there can be millions of layers of 2D materials which generates its unique properties. Image credit: Olov Planthaber/Linköping University
Since the discovery of graphene, the field of research in extremely thin materials, so-called 2D materials, has increased exponentially. The reason is that 2D materials have a large surface area in relation to their volume or weight. This gives rise to a range of physical phenomena and distinctive properties, such as good conductivity, high strength or heat resistance, making 2D materials of interest both within fundamental research and applications.
“In a film that’s only a millimetre thin, there can be millions of layers of the material. Between the layers there can be a lot of chemical reactions and thanks to this, 2D materials can be used for energy storage or for generating fuels, for example,” says Johanna Rosén, professor in Materials physics at Linköping University.
Three-step process
The largest family of 2D materials is called MXenes. MXenes are created from a three-dimensional parent material called a MAX phase. It consists of three different elements: M is a transition metal, A is an (A-group) element, and X is carbon or nitrogen. By removing the A element with acids (exfoliation), a two-dimensional material is created. Until now, MXenes has been the only material family created in this way.
The Linköping researchers have introduced a theoretical method for predicting other three-dimensional materials that may be suitable for conversion into 2D materials. They have also proved that the theoretical model is consistent with reality.
To succeed, the researchers used a three-step process. In the first step, they developed a theoretical model to predict which parent materials would be suitable. Using large-scale calculations at the National Supercomputer Centre, the researchers were able to identify 119 promising 3D materials from a database and a selection consisting of 66,643 materials.
From theory to lab
The next step was to try to create the material in the lab.
“Out of 119 possible materials, we studied which ones had the chemical stability required and which materials were the best candidates. First, we had to synthesise the 3D material, which was a challenge in itself. Finally, we had a high-quality sample where we could exfoliate and etch away a specific atom layers using hydrofluoric acid,” says Jie Zhou, assistant professor at the Department of Physics, Chemistry and Biology.
The researchers removed yttrium (Y) from the parent material YRu2Si2, which resulted in the formation of two-dimensional Ru2SixOy.
But to confirm success in the lab, verification is necessary – step three. The researchers used the scanning transmission electron microscope Arwen at Linköping University. It can examine materials and their structures down at the atomic level. In Arwen it is also possible to investigate which atoms a material is made up of using spectroscopy.
“We were able to confirm that our theoretical model worked well, and that the resulting material consisted of the correct atoms. After exfoliation, images of the material resembled the pages of a book. It’s amazing that the theory could be put into practice, thereby expanding the concept of chemical exfoliation to more materials families than MXenes,” says Jonas Björk, associate professor at the division of Materials design.
Endless applications
The researchers’ discovery means that many more 2D materials with unique properties are within reach. These, in turn, can lay the foundation for a plethora of technological applications. The next step for the researchers is to explore more potential precursor materials and scale up the experiments. Johanna Rosén believes that future applications are almost endless.
“In general, 2D materials have shown great potential for an enormous number of applications. You can imagine capturing carbon dioxide or purifying water, for example. Now it’s about scaling up the synthesis and doing it in a sustainable way,” says Johanna Rosén.
The study was funded by the Knut and Alice Wallenberg Foundation, the Wallenberg Initiative Materials Science for Sustainability (WISE), the Göran Gustafsson Foundation for Research in Natural Sciences and Medicine, the Swedish Foundation for Strategic Research, the European Union, the Swedish Research Council and the Swedish Government Strategic Research Area in Materials Science on Advanced Functional Materials, AFM, at Linköping University.

These techniques are essential for defining the structure and functionality of semiconductor devices, influencing their performance and properties.
In the realm of etching, various methods such as chemical, physical, and plasma etching are utilized, each offering distinct advantages in terms of precision, speed, and selectivity. On the other hand, deposition techniques encompass processes like physical vapor deposition (PVD), chemical vapor deposition (CVD), and atomic layer deposition (ALD), each tailored to deposit specific materials with precise control over thickness and composition.
Etching Techniques in Semiconductor Fabrication
In semiconductor fabrication, etching techniques are employed under the guidance of an expert such as Nav Sooch to pattern the semiconductor material, allowing the formation of transistors, interconnects, and other essential components of integrated circuits. Among the common etching methods, plasma etching stands out for its ability to achieve high etch rates and precise feature definition. Plasma, generated by applying radiofrequency (RF) energy to a gas mixture, reacts with the material surface, leading to its removal.
Another prominent etching technique is reactive ion etching (RIE), which utilizes chemically reactive ions to etch the material selectively. RIE offers superior anisotropy and pattern transfer capabilities, making it well-suited for creating high-resolution features. Additionally, wet etching, involving immersion in liquid chemical solutions, is still utilized for certain applications, particularly in removing sacrificial layers or cleaning substrates before deposition.
Deposition Methods in Semiconductor Manufacturing
Deposition plays a vital role in semiconductor fabrication by adding thin layers of materials onto the substrate, forming structures such as gates, electrodes, and insulation layers. Physical vapor deposition (PVD) is a widely used technique where material is evaporated from a solid source, then condensed onto the substrate surface, forming a thin film. PVD offers excellent control over film thickness and uniformity, making it suitable for producing metallic layers and thin films.
In contrast, chemical vapor deposition (CVD) involves the reaction of precursor gases to deposit materials onto the substrate surface. CVD enables the deposition of a wide range of materials, including silicon dioxide, silicon nitride, and various metals, with precise control over film properties. Atomic layer deposition (ALD) takes deposition precision to the atomic level, enabling the sequential deposition of atomic layers with exceptional uniformity and conformality, critical for advanced semiconductor devices.
Challenges and Advances in Etching and Deposition
Despite the advancements in etching and deposition techniques, semiconductor manufacturers face challenges in achieving ever-shrinking feature sizes and maintaining uniformity across large-area substrates. The relentless drive towards miniaturization demands innovations in process control, materials science, and equipment design to overcome these challenges. Moreover, the emergence of new materials, such as novel dielectrics and metal alloys, necessitates the development of deposition techniques capable of accommodating diverse material properties.
In response to these challenges, researchers and engineers are exploring novel approaches such as directed self-assembly and atomic-scale patterning to push the boundaries of semiconductor fabrication. Directed self-assembly harnesses the intrinsic properties of block copolymers to create nanoscale patterns with remarkable precision, offering a promising route for next-generation lithography. Similarly, atomic-scale patterning techniques like electron beam lithography and helium ion microscopy enable the direct writing of features at the atomic level, bypassing the limitations of traditional photolithography.
Future Perspectives and Industry Trends
Continued advancements in etching and deposition techniques are expected to revolutionize semiconductor manufacturing, driving the industry towards higher levels of efficiency, reliability, and scalability. One emerging trend is the integration of 3D stacking technologies, where multiple layers of transistors and interconnects are vertically stacked to increase device density and performance. This approach, facilitated by advanced etching and deposition processes under the guidance of an expert such as Nav Sooch, holds promise for overcoming the limitations of traditional 2D scaling and unlocking new levels of computational power and energy efficiency.
Additionally, the development of novel materials such as two-dimensional (2D) materials and metal-organic frameworks (MOFs) opens up exciting opportunities for exploring unconventional device architectures and functionalities, further fueling innovation in etching and deposition techniques. As semiconductor manufacturers navigate the complexities of Moore's Law and embrace new paradigms in device design and fabrication, the role of etching and deposition will remain central in shaping the future of semiconductor technology.
Etching and deposition techniques are indispensable pillars of semiconductor fabrication, enabling the precise manipulation of materials and the creation of intricate device structures. From etching nanoscale features under the guidance of an expert such as Nav Sooch to depositing thin films of materials, these processes underpin the production of integrated circuits and semiconductor devices that power our modern world. As semiconductor technology advances and new challenges emerge, continued innovation in etching and deposition will drive the development of next-generation devices and pave the way for future technological breakthroughs.
