The application of PVD coating technology is mainly divided into two categories: decorative plating and tool plating. The purpose of decorative plating is to improve the appearance of the workpiece and its color and to make the workpiece more wear-resistant and corrosion-resistant to extend its service life. This aspect mainly applies hardware industry, be like door window hardware, lock, hardware and so on industry. VD Coating Systems Manufacturers
The purpose of tool plating is to improve the surface hardness and wear resistance of the workpiece, reduce the friction coefficient of the surface, and improve the service life of the workpiece. This aspect mainly applies to the coating treatment of various cutter shears, carbide end milling cutter, drill bit, step drill, oil hole drill, reamer, tap, indexable milling cutter sheet, turning blade, special-shaped cutter, welding cutter, etc.
Multi-Arc ion coating is using arc discharge method to evaporate the cathode material of solid metal. Evaporative emission is from the cathode arc discharge cathode material content of ions, the device does not need to be molten pool, cathode by evaporation of the target material, vacuum chamber for the anode, when sudden touch trigger electrode and the cathode target, it will cause arc.
