The principle of PVD coating technology of vacuum multi-arc ion plating machine
Physical vapor deposition (PVD) technology is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating and vacuum ion coating. Compared with the three types of PVD technology, the corresponding vacuum coating equipment includes vacuum evaporation coating machine, vacuum sputtering coating machine and vacuum ion coating machine. In the past ten years, vacuum ion plating technology has developed the fastest. It has become one of the advanced surface treatment methods. PVD coating, we usually call it vacuum ion coating; PVD coating machine usually refers to vacuum ion coating machine
Vacuum multi-arc ion plating machine (the principle of PVD coating technology is: under vacuum conditions, using low-voltage high-current arc discharge technology, vaporize the target and ionize the evaporation material through gas discharge, and the evaporation material or its reaction product is deposited under the action of an electric field On the workpiece. The difference between samPVD coating and traditional electroless plating is that they both belong to the category of surface treatment, in which one material can cover the surface of another material in a certain way. The difference between the two is: PVD coating The adhesion between the layer and the surface of the workpiece is greater, the hardness is higher, the wear resistance is better, the corrosion resistance is good, the coating film performance is more stable; the PVD coating can be plated with a wider variety of coating films, and various coating colors can be plated More and more beautiful; PVD coating does not produce toxic or polluting substances.
