Physial vapor deposition (PVD) is a generic term for vacuum plating processes involving bombardment of the surface by energetic ions to enhance coating adhesion and improve coating structure. It is a common industrial process.olerances: PVD coatings are too thin to affect part tolerances, and in general will reflect the surface roughness of the base material. However, it is often necessary to plate the part surface with nickel and chromium prior to applying the PVD coatings. The combination can be thick enough to affect tolerances.
