Evaporation coating equipment and technology
vacuum evaporation coating equipment is mainly used for evaporating metal film (aluminum, chromium, tin, stainless steel, etc.) and colorful film imitating gold film on the surface of treated plastics, ceramics, and other products, so as to obtain bright, beautiful, and inexpensive plastic and ceramic surface metalized products.
Widely used in arts and crafts, decoration, lamps, furniture, toys, wine bottle caps, women’s heels, and other fields, JTPZ multi-function coating technology, and equipment (with radio frequency plasma polymerization evaporation coating machine), is designed for the automobile, motorcycle lamps, and lanterns, evaporated aluminum plating and radio frequency plasma plating protective film are completed in a vacuum chamber, this kind of coated lamps and lanterns have “three prevention” functions.
Radiofrequency plasma polymerization film is also used in optical products, magnetic recording media, military defense protective film, moisture-proof antireflective film, anti-rust and anti-corrosion, wear-resistant, and hard film.
Users choose to spray primer, aluminized film, protective film, or lamp substrate in a vacuum chamber for pre-treatment (no primer), aluminized film, and protective film process.
Equipment and technology of plasma diffusion coating for vacuum plating
Ion nitriding: under the condition of glow discharge, elements such as N and C can be infiltrated into parts and molds to significantly improve surface hardness, fatigue resistance, and corrosion resistance. compared with the overall nitriding treatment time is short, has low humidity, small deformation, surface properties can be controlled, and can be used in a variety of iron and steel and titanium alloy structures, molds, and stainless steel products.
Plasma chemical vapor deposition equipment and technology (ion nitriding, nitrocarburizing) plasma chemical vapor deposition (PCVD) is a new type of pulsed DC plasma-assisted hard coating technology.
In a vacuum furnace with a certain pressure and temperature, a proper proportion of different working gases are added, and a uniform plasma is produced by glow discharge under the action of pulse voltage.
Various hard films such as TiN, TiC, TiCN, (Ti, Si) N, (Ti, Si) CN, and multilayer composite films can be formed on the surface of the treated workpiece under different process conditions, and the microhardness is as high as HV2000–2500.
Compared with CVD and PVD, PCVD technology can realize ion nitriding, Carburizing, and coating in the same furnace, and the infiltration compound process can be realized with high efficiency.
The equipment is suitable for parts and molds that require improved surface wear resistance, corrosion resistance, high-temperature oxidation resistance, and fatigue resistance.
The treated materials mainly include: high-speed steel, hot and cold steel, hot and cold die steel, structural steel, stainless steel, titanium alloy, cemented carbide, and so on.
