PVD Technology
PVD is the abbreviation of physical vapor deposition. PVD is the technology of material evaporation deposition in vacuum state. Vacuum chamber is the necessary condition to avoid the reaction of evaporated material and air. PVD coating is used to prepare new products with additional value and characteristics, such as brilliant color, wear resistance and friction reduction. The PVD process is used to form the coating by condensing most of the metal materials and combining them with gases, such as nitrogen. The matrix material is transformed from solid state to gas state, and is ionized by heat energy as received in the arc process, or by kinetic energy as in the sputtering process. PVD technology is environmentally friendly and pollution-free. In general, Huicheng vacuum focuses on PVD coating.
