PVD Coating Machine For Metal Nitride Coating With Gold Finish A PVD coating machine performs physical vapor deposition, a high-tech process used to deposit thin films onto various substrates. The process occurs inside a high-vacuum chamber where a solid material, known as the target, is vaporized. This vaporization can be achieved through several methods, including sputtering, where high-energy ions bombard the target, or evaporation, where the target is heated until it
