How much arc ion coating machine furnace structure

Vacuum evaporation coating machine vacuum equipment used by the structure of the material, should have a certain vacuum performance and some necessary performance. With sufficient air tightness. Manufacture vacuum equipment used materials must be compact structure, the material surface and internal shall not have cracks, holes or other defects may cause leakage. To avoid using porous, rough structure of the material, material absorption and adsorption gas should be less as far as possible, and easy for deaeration, make the material in a vacuum has smaller abandon rate; Saturation vapour pressure is low enough, without affecting the vacuum degree of system; Good mechanical strength.
  Can splash control sputtering coating machine must have enough mechanical strength and stiffness, the pressure difference under the not damage and deformation under the working conditions; Material should be used in the chemical stability is good, not easy to oxidation and corrosion, does not react with a working medium in the system. Temperature stability is good. Could reach in the working process of the maximum and minimum temperature range, can maintain the vacuum performance, mechanical properties, physical properties, and chemical properties. Easy cleaning \ processing, easy to get high smooth surface.
