Overview of vacuum coating

Vacuum coating is an important aspect in the field of vacuum application. It is a new technology based on vacuum technology, using physical or chemical methods, and absorbing a series of new technologies, such as electron beam, molecular beam, ion beam, plasma beam, radio frequency and magnetic control, to provide a new technology for scientific research and practical production. Simply speaking, the method of evaporating or sputtering metal, alloy or compound in vacuum to make it solidify and deposit on the coated object (called substrate, substrate or substrate) is called vacuum coating.China PVD Coating Machine Suppliers
