Physical Vapor Deposition (PVD) is used to coat and paint many different surfaces; usually, it’s used on tools and equipment to ensure a clean paint job. PVD works by vaporizing molecules from their solid phase into a gas. Once the gas comes into contact with the object that is being painted, the molecules are transformed back into their solid state. The process gradually builds a film on the object that is being coated until the desired thickness is reached.
When PVD is used in vacuum engineering for reactive depositing, the materials react with different gases; the gases form a film of mixed materials like carbide, oxide or nitride. PVD is a great alternative to methods like electroplating and painting. You are using a vapor to coat an object, so you can control the thickness of the material that is being used; you easily control the desired finish and variable thickness of your paint.
When PVD is used to paint surfaces on a large scale, it results in the reduction of hazardous waste; this is especially true when it is compared to processes like electroplating and metal finishing. In the past, harsh chemicals were needed to plate metal; and many of these made their way into the environment.
PVD is a great alternative to traditional methods; there is almost no hazardous waste. You simply vaporize your materials and wait for them to coat the object that you are painting. PVD is compatible with all metals and most plastics, so it’s a great option for anyone who needs a strong and durable coating.
