Ion coating machine coating pretreatment process

               

  Working principle of ion coating machine is certain vacuum condition, by gas discharge, work or membrane material part of gas ionization, evaporation in the gas ion or material under the action of the bombardment of ions, the evaporation or reactants form a thin film deposited on the substrate surface. Ion coating machine coated in one of two ways, one is evaporation ion plating, the other is a sputtering ion plating. Evaporation is ion plating by heating membrane material, to produce metal steam, and then through different ways to motivate steam discharge, ionization deposited into a film. Sputtering ion plating is produced by high-energy ion sputtering film material on the surface of metal particles, then in gas ionization discharge space into a metal ion, the deposition film on the substrate. Vacuum ion plating for sedimentary hard film, widely used, such as cutting tools, wear-resistant parts surface.
Before with ion coating machine made plating film, is needs a sample test according to the needs of users, the following brief introduction:
1, first, and customer communication, to understand the performance and usage of samples;
2, analysis of samples, the performance, surface state, etc.;
3, choose before processing link;
4, depending on the type of surface shape, pollutants such as choosing pre cleaning;
5, test before treatment effect;
6, test samples, if qualified, compiling process, formally put into production.
