PVD treatment surface means"Physical Vapor Deposition", 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 sputter coating and vacuum ion plating.
But at this stage, the PVD coating can't be replaced by chemical plating, and in addition to
the stainless steel material surface can be directly for PVD coating, before PVD coating in
many other material artifacts, all need to make chemical plating Cr first.
The similarities of the PVD coating and traditional chemical plating,both belong to the
category of the surface treatment, and both through certain way makes a material covered
on the surface of another material.The differences is :the binding force of the PVD coating
film and the surface of the workpiece is larger, film hardness is higher, better wear
resistance and corrosion resistance, the performance of the membrane layer is more
stable; the layer membrane type which PVD coating can plating is more widely, the various
membrane layer color can be coated more and more beautiful; PVD coating does not
produce toxic or contaminated material.
