PVD multi arc ion coating machine is an efficient, harmless, and pollution-free ion coating equipment, which has the advantages of fast deposition speed, high ionization rate, high ion energy, simple equipment operation, low cost, and large production volume.The main functions of PVD multi arc ion coating machine include coating various hard metal films, metal compound films and decorative films on the surfaces of metals, ceramics, glass and other materials. It has the characteristics of fast pumping speed, stable vacuum, large loading capacity, and good coating uniformity. Its working principle is to apply vacuum arc discharge technology to evaporation source technology, which ignites the evaporation source (cathode) in a vacuum environment, forms self-sustaining arc discharge between the cathode and the anode, and releases ions of cathode material from the bright spot of the cathode arc. This technology can not only coat the surface of metal products, but also the surface of non-metal products. It can coat metal films, titanium nitride, titanium carbide, zirconium nitride, chromium nitride, as well as compound films such as titanium, nickel, chromium, copper, multi-layer superhard films, titanium nitride doped gold films, and alloy films, and complete the entire processing process in a very short time.
