PVD stands for physical vapor deposition, which is also called vacuum plating, including multi arc, magnetron sputtering, thermal evaporation.PVD film can be used for decorative purpose, functional purpose and optical purpose, such as golden furniture, high hardness drill and Low-E glass.It is green

PVD film has decorative and functional.As for decorative, it is easy to be scratched since its thickness is just 0.3-1um. Also coating temperature only ranges from 100-300 degree Celsius. As we know, high temperature will increase intermolecular distance, then improve film adhesion and compactness.A

Firstly, PVD means physical vapor deposition, also called vacuum plating or vacuum coating, so PVD jewelry means jewelry with PVD coating.In detail, PVD coating technology for jewelry can be cathodic arc or magnetron sputtering. Cathodic arc is with fast deposition rate, but rough film particles, wh
