Multi-arc ion coating equipment adopted plasma vacuum coating technology, which is united electro-arc and magnetron sputtering technique. It suited for coating goldenlike film, TiN film, ZrN film, CrN film on the surface of metal and nonmetal material, such as stainless steel, hard alloy, ceramic etc. The physical and chemical performances of products such as wearable, acidproof, ormamental are improved. The coater is widely used in high-grade tableware, watch, porcelain, hardware industry.
