What are PVD and CVD coatings?
PVD is the abbreviation of Physical Vapor Deposition. PVD is a process that produces a family of coatings. The staple of the family is titanium nitride (TiN) however: chromium nitride (CrN), aluminum titanium nitride (AlTiN) are other examples of PVD coatings.
CVD is the abbreviation Chemical Vapor Deposition. Chemical vapor deposition is a chemical process used to produce high-purity, high-performance solid materials. One such material is Diamond-Like-Carbon (DLC). DLC coatings feature excellent hardness, wear and low friction properties under dry or deficient lubrication conditions. They are ideally suited for mechanical assemblies with sliding and rolling movements
