As for treatment, we think there has pre-treatment and after-treatment.Pre-treatment includes cleaning and baking. Some items like sheets doesn’t need baking since it is solid part.After PVD coating, in thermal evaporation, we have to use finish paint to cover the film to reach protective purpose. I

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
