PVD coating is extremely important in the world of metals and finishing. It has innumerable applications across many different industries and products. The reasons for this are many: it is very hard, it does not corrode easily, and it is highly resistant to wear and tear. These qualities make PVD coating quite the wonder. In this article, we explore some of the applications of PVD
What is PVD?
Before discussing what the applications of PVD are, let us take a look at what PVD is. Physical Vapor Deposition, or PVD, as it is commonly called, refers to a variety of thin film deposition techniques. In these techniques, there is a solid material that is first vaporized in a vacuum environment. This material is then deposited on substrates as a pure material or alloy composition coating. PVD coatings are used in many different kinds of products and industries. They can be found in device applications such as computer chips or in optical applications like self-cleaning tinted windows or eye glasses. Products such as solar panels, semiconductor devices, durable protective films, microchips, and a host of medical devices all use PVD coating because it contributes to their performance attributes.
Since PVD coatings are highly durable and resistant to corrosion and scratches, it is used for many different applications. Following are some of the applications of PVD coatin
Automotive Industry: No one can deny the importance of the fuel economy in recent years. As a result, automotive companies have put a lot more focus on the reduction of weight and the loss of energy due to friction. These factors become especially important in motor sports.
Cutting Tools: PVD has revolutionized cutting tools in the metal cutting industry. This is one of the most important industrial applications of modern coating technology. Applications that require very sharp edges, such as grooving, threading, and end milling use PVD coated tools. PVD coated tools are also used in those cutting applications that have a very high requirement for a tough cutting edge. Drilling is an example of one such application.
Injection Molding Tools: Injection molding refers to the process of producing parts by injecting molten material into a mold, or mold. Injection molding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Plastic granules are heated to their melting point and then injected at very high pressure into a mold through a nozzle. PVD coatings are used for these injection tools.
Punches and Forming Tools: Punches and forming tools require resistance against abrasion and wear and tear. This is a quality that PVD coatings have. They are very hard and highly resistant to wear. As a result, PVD coatings are ideal to prevent bunches and forming tools from being worn out easily. This significantly increases the lifetime of these tools. TV.
Screens & Data Displays, Architecture: Glass plays a very important role in innumerable applications because of its stability and the fact that it is resistant to scratches. Furthermore, it is also highly transparent. Data displays and glass panes in architecture are just some of the examples of places where glass can be used. However, glass can be improved further by using optical coatings of PVD. Whether it is for the flat lay panel industry or glare reducing sunglasses and eye glasses, PVD coating has a role to play.
Decorative Applications: PVD coatings are very high quality surface finishes and used for many decorative finishes. Watches use PVD coatings. Manufacturers of sanitary and door hardware often market PVD coated products with long time guarantees specifically on their appearance. Compared to the traditional electroplated coatings, PVD ceramic coatings are harder and more resistant to wear and tear, do not tarnish or discolor, and are very resistant to corrosion too. PVD coatings also do not suffer when under UV radiation
PVD is a very superior kind of coating. At Diamond Brite Metals, we are pleased to offer metal polishing combined with PVD in order to create a unique and aesthetically superior product. Diamond Brite Metals offers the following finishes in conjunction with PVD: #4 (satin & hairline), #6, #8 Mirror, and Bead Blasted, and Non-Directional (angel hair or vibration).
