Application And Progress Of Vapor Deposition Technology

Application and Progress of vapor deposition technology

 The application of vapor deposition technology involves many fields. It is widely used only in improving the wear and corrosion resistance of mechanical parts. If TiN, TiC, Ti (CN) films prepared by the above method have high hardness and wear resistance, TiN film plating on high-speed steel tools can be said to be a revolution of high-speed steel tools, the cutting surface of the tool coated with 1~3μm TiN film can increase its service life more than 3 times. At present, in some developed countries, 30%~50% of the sharpening tools are plated with wear-resistant layers. Other metal oxides, carbides, nitrides, cubic boron nitride, diamond-like films, as well as a variety of composite films also show excellent wear resistance. Ag, Cu, Culn, AgPb, and other soft metals and alloy films prepared by physical vapor deposition and chemical vapor deposition, especially MoS, WS, and PTFE films plated by sputtering and other methods, have good lubrication and wear reduction effects. Al, 0, TiN films obtained by vapor deposition has good corrosion resistance and can be used as protective films for some matrix materials. The corrosion resistance of amorphous films containing chromium is higher. At present, ion plated Al, Cu, Ti films have been used in parts of the aviation industry instead of electroplating products. Thermal corrosion-resistant alloy coatings prepared by vacuum coating and thermal barrier coatings developed by vacuum coating have been used in many series. As an important branch of ion beam technology, ion implantation has increased the service life of molds, tools, tools, and parts such as aviation bearings, rollers, turbine blades, and nozzles by 1 to 10 times.
