Brief Description Of The Comparison Between PVD Vacuum Coating And Water Electroplating

- Jun 05, 2018-

PVD and water electroplating are both methods of surface treatment, which refers to covering one material on the surface of another material in a certain way to obtain one or more layers coatings with certain functions (wear resistance, corrosion resistance, heat resistance, electrical conductivity, etc.).


Water electroplating is widely used due to its relatively simple process, and it has lower requirements from the equipment to the environment compared with PVD. However, the general plating material of water electroplating is "hexavalent chromium", which is a non-environmental material and causes serious environmental pollution. The coating materials used for vacuum coating is more extensive and meets environmental requirements. The film material is deposited on the surface of the workpiece by plasma ionization in the vacuum state. So, the PVD coating has higher bonding force, higher hardness, higher friction resistance, corrosion resistance, and more stable coating performance without toxic or contaminating substances and gases, it has no adverse impact on the environment and in line with the development direction of modern green manufacturing.
