Taking use of multi arc ion coating technology can do coating film on metal,alloy,and electrically conductive material(substantially non-conductive material) (using high-frequency bias). Multi-arc Ion plating film can be deposited by metal film, multi-alloy film, compound film; Can be single plated coating and also composite coating film can also be plated coatings and nano-multilayer coating gradient. br br Vacuum ion plating equipment coating products, including drills, milling cutters, gear cutters, broaches, taps, scissors, shave blades, molds, injection molding, magnetic forming die, punching die, automotive and medical equipment, and other wear parts. br br br br Ion plating technology is particularly suitable for the deposition of hard film. Ion plated hard and wear resistant coating film as super-hard anti-wear protection film is widely used in tooling, film tools, wear parts. Common membrane system comprises TiN, ZrN, TiAIN, TiC, TiCN, CrN, AI2O3 and the like. In addition, there are more hard DLC (DLC), TiB2 and carbon and nitrogen (CNX) film.
