Introduction to basic knowledge of PVD coating of vacuum coating machine

2023-03-03

PVD (Physical Vapor Deposition) technology is mainly divided into three categories, vacuum evaporation coating, vacuum sputtering coating and vacuum ion coating. Compared with the three classifications of PVD technology, the corresponding vacuum coating equipment also includes vacuum evaporation coating machine, vacuum sputtering coating machine and vacuum ion coating machine.

Vacuum conditions in the process of vacuum evaporation coating machine

2023-03-03

In the vacuum chamber, when the particle concentration in the gas phase and the pressure of the residual gas are low enough, these particles can keep flying in a straight line from the evaporation source to the substrate, otherwise, they will collide and change the direction of motion.

Why use high-purity gas in vacuum coating

2023-03-03

After high-purity coating metal (such as aluminum) is evaporated at high temperature, it will freely fly away and settle on the surface of the workpiece to form a coating. Argon is a protective gas to prevent the oxidation reaction from affecting the coating quality. In the work of vacuum ion coating equipment, the color of liquid gas will be different when different gases are selected.
