Surface treatment PVD means Physical Vapor Deposition, is a variety of vacuum deposition
methods used to deposit thin films by the condensation of a vaporized form of the desired
film material onto various workpiece surfaces.
PVD technology is mainly divided into three categories: Vacuum evaporation coating, vacuum
sputtering and vacuum ion plating. However, at this stage, PVD coating is not a substitute for
chemical plating, and it can only make PVD coating directly on stainless material surface,if other
material on the workpiece, need to make chemical plating chromium.
The same point of the PVD coating and the traditional chemical plating is they are all belong to
surface treatment ,all through a certain way to make one material covering to the surface of
another material .The different point is the bonding force of the PVD coating film layer and the
surface of the workpiece are more greater, the hardness of the film is higher, the abrasion
resistance and corrosion resistance is better, and the film performance is more stable;
wider variety of the PVD coating ,the film can be plated more prettier; would not produce
toxic or polluting substances.
