The advantages of PVD ion coating and vacuum evaporation coating

The specific principle of ion plating (PVD coating) technology mainly refers to the use of high-current, low-voltage arc discharge technology in a vacuum environment, and the rational use of gas discharge, which can promote the rapid evaporation of the target material, and evaporate gas and substances Both can be rapidly ionized, and then accelerated by the electric field, thereby prompting a large amount of reaction products and vaporized substances to gather on the workpiece. Compared with vacuum evaporation coating, PVD ion coating has the following advantages due to its various characteristics: (1) Ion has better diffraction performance, and can process various complex plated workpieces; (2) The surface of the workpiece and the film has a strong bonding force, so it has higher wear resistance and durability; (3) There are many types of coatings that can be coated; (4) The film has a faster deposition rate and has Higher production efficiency; (5) It has a relatively stable film performance, and its safety is also very high.　　PVD technology is more suitable for forming, stamping, stretching and other molds, turning tools, drills and other tools and precision parts. After the coating technology is applied to the mold, the anti-wear force and hardness can be effectively improved, and the friction coefficient can be reduced at the same time, so that the service life of the workpiece can be prolonged. Normally, compared with the untreated workpiece , Its life can be increased by 3-10 times. Up to now, the more common coatings mainly include: TiCN, CiN, etc., and various coating treatment technologies have obvious differences in their uses and characteristics.
