What is a coating?

The evaporation material is ionized and deposited on the cathode. It is called Ion Plating by plating in an ion state. Ionization of the evaporated particles converts ArGas into plasma, and while the evaporation particles pass through the plasma layer, they are hit by electrons and become positive ions, which are attracted to the cathode and collide. However, not only ions, but also evaporation molecules, electrons, gas molecules, etc., collide on the substrate as the cathode, and in addition to the thermal effect, sputtering, ion implantation, and the resulting ion mixing (mixing) surface chemical reactions are promoted. It creates a compound coating film. In addition, in order to improve the thermal role of ions in plasma, a high negative voltage is applied to the substrate, and at this time, the ions have a kinetic energy as large as the negative voltage.
