Coating technology of PVD vacuum coating equipment(machine)
The film layer plated by PVD coating technology has the characteristics of high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, etc., and the life of the film is longer; at the same time, the film can greatly Improve the appearance of the workpiece.
PVD film can be directly plated on stainless steel and cemented carbide. Die castings such as zinc alloy, copper, iron, etc. should be electrolessly plated with chromium before they are suitable for PVD plating. PVD coating technology is an environmentally friendly surface treatment method that can truly obtain micron-level coatings and pollution-free. It can prepare a variety of single metal films (such as aluminum, titanium, zirconium, chromium, etc.), nitride films (TiN (titanium gold) ], ZrN [Zirconium Gold], CrN, TiAlN) and carbide films (TiC, TiCN), and oxide films (such as TiO, etc.). The thickness of the PVD coating film is micron level, and the thickness is relatively thin, generally 0.1μm～5μm, and the thickness of the decorative coating film is generally 0.1μm~1μm, so the surface of the workpiece can be improved without affecting the original size of the workpiece. It has various physical and chemical properties, and can maintain the size of the workpiece basically unchanged, and no further processing is required after plating.
