Introduction to the principle of PVD multi-arc ion coating machine



PVD coating machine




The principle of PVD arc ion plating is based on the theory of cold cathode vacuum arc discharge. The core technology of the multi-arc ion coating machine is its arc evaporation source. The evaporation source of multi-arc ion coating machine is a special cold cathode arc self-evaporation and self-ionization solid evaporation source.


1. Compared with the traditional evaporation source, the arc evaporation source of the multi-arc ion plating machine has obvious advantages


2. The coating has high density, long service life and high strength;


3. As a solid source for arc evaporation, its shape, size and position can be changed;


4. Large working vacuum range;


5. Higher ion energy;


6. High ionization rate of 60%-80%;


7. High deposition rate, such as tin, can obtain a high deposition rate of 100nm/S~1000nm/S.
