PVD Vs CVD: Which One Is Better?
Both Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD) and both are very well known film coating methods. In this article, you will learn about the different aspects of PVD coating and CVD processes as they work, advantages, disadvantages and many others. CVD Coating CVD stands for Chemical Vapor Evaporation, which is a thin film coating process. During the CVD process, one or more volatile precursors are introduced into the reaction chamber along with the substrate. The precursors react or break down on the surface of the seed to form a coating layer. Waste gas escapes from the reaction chamber through diffusion. Because of the actual chemical reaction that occurs on the substrate surface, this process is called Chemical Vapor Deposition. PVD Coating Meanwhile, Physical Vapor Deposition(PVD) is – without surprise, given its name – deposition by physical rather than chemical means. One of the most popular physical methods, which Deep Coat uses when cleani...
