PVD vacuum coating is a surface treatment process that uses sputtering, evaporation or ion plating techniques to form a thin film on a substrate using titanium, gold, graphite, crystal and other metal or non-metal, gas and other materials in a vacuum. Compared with the traditional chemical coating method, vacuum coating has many advantages: such as no pollution to the environment, it is a green process; no harm to the operator; strong film layer, good density, strong corrosion resistance, and uniform film thickness. The methods often used in vacuum coating technology mainly include: evaporation coating (including arc evaporation, electron gun evaporation, resistance wire evaporation, etc.), sputtering coating (including DC magnetron sputtering, intermediate frequency magnetron sputtering, radio frequency sputtering, etc.) ), these methods are collectively referred to as Physical Vapor Deposition, or PVD for short.
　　 The corresponding chemical vapor deposition (Chemical Vapor Deposition) is abbreviated as CVD technology. The "IP" (ion plating) ion plating is commonly referred to in the industry because various gas ions and metal ions participate in the film formation process and play an important role in the PVD process technology. In order to emphasize the role of ions, they are collectively called ions. Coating. 　　Vacuum coating is a technology to produce thin film materials. The atoms of the material in the vacuum chamber are separated from the heating source and hit the surface of the object to be plated. This technology is used in the production of aluminum coatings on compact discs (CDs) and metal coatings on printed circuit boards by masks. The film layer is prepared in a vacuum, including plating crystalline metal, semiconductor, insulator, and other elemental or compound films. Although chemical vapor deposition also uses vacuum means such as reduced pressure, low pressure or plasma, vacuum coating generally refers to the use of physical methods to deposit thin films. There are three forms of vacuum coating, namely evaporation coating, sputtering coating and ion plating. Evaporation coating is deposited on a solid surface by heating and evaporating a certain substance, which is called evaporation coating.
