(PVD) Physical Vapour Deposition (PVD) is a process used to coat surfaces with thin films of hard, durable materials such as titanium nitride, chromium nitride, and stainless steel. PVD is a vacuum-based process in which a gas is decomposed by a high-energy source such as an electron beam to form a vapour, which is then deposited onto the substrate. This results in a thin film of material being applied to the substrate, which is often used to improve the durability, wear resistance, and corrosion resistance of the surface. It is a popular coating process in watchmaking due to its ability to create thin, highly durable coatings.
