PVD is the abbreviation of Physical Vapor Deposition (PVD). It refers to the arc discharge technology with low voltage and high current, which evaporates the target material and ionizes the evaporated material and gas by gas discharge under vacuum condition, and makes the evaporated material and its reaction products deposit on the workpiece by the acceleration of electric field. If gradient is to be made, a baffle (MASK) will be added between the target and the workpiece. The thickness o... read more
What are the advantages of PVD coating over traditional electroplating? PVD coating and traditional electroplating are similar, both belong to the category of surface treatment, both are to make a certain way to cover the surface of another material. The difference between the two is that PVD coating film layer and the surface of the workpiece have higher adhension, higher hardness of the film layer, better wear resistance and corrosion resistance, and more stable performance than electroplating... read more
