4. The vacuum coating process is a physical method of plating metal onto a substrate, not a chemical method. The process of coating is carried out in a vacuum chamber where the metal melts and reaches its vaporization point, becoming gaseous. A relatively homogeneous coating is created on the target substrate after the gaseous molecules condense there after traveling along the line of sight. The vacuum system contains a sealed chamber where the coating process takes place. Outside the enclosure, there are multiple pumps pumping air out to the pressure required for the process. A power source supplies the required voltage to an electrode connected to a series of insulators containing tungsten filaments that carry the metal to be evaporated.
