Vacuum Ion Plating (PVD) Process

Vacuum ion plating (PVD) process

As we all know, there are many methods of coating, gas-phase generation method, oxidation method, ion injection method, diffusion method, electroplating method, coating method, liquid phase generation method, etc. The gas-phase generation method can be divided into physical vapor deposition, chemical vapor deposition, and discharge polymerization. What we mainly introduce today is the Physical Vapor Deposition method, namely PVD (Physical Vapor Deposition). Because this method is basically carried out in a vacuum environment, it is also called vacuum ion plating technology.
PVD coating technology refers to the vacuum condition, the use of low voltage, large current arc discharge technology bombardment target, the use of gas discharge, the target evaporation, and the evaporation of material and gas are ionized, using the acceleration of the electric field, so that the evaporation of material and its reaction products deposition on the workpiece.
The product coating process is a high vacuum environment, the air pressure in the coating machine is very low, during the vacuum process, grease, impurities, and water on the surface of the product will overflow, which will lead to vacuum instability, so the product surface and internal must not contain non-metallic substances, the surface must also ensure absolute cleanliness.
The vacuum coating process needs to go through a material inspection, cleaning surface, high-temperature baking, hanging tools, coating (PVD), coating material, wire drawing treatment (antique copper), nano anti-fingerprint processing, baking, hanging tools, inspection, packaging and more than a dozen processes, to complete.
