High current arc discharge technology of vacuum coating machine

High current arc discharge technology of vacuum coating machine

The specific principle of PVD coating (ion coating) technology of vacuum coating machine is that under vacuum conditions, arc discharge technology of low voltage and high current is used, and gas discharge is used to evaporate the target material and ionize the evaporated material and gas. The acceleration of the electric field causes the vaporized substances and their reaction products to be deposited on the workpiece. .

Vacuum coating machine PVD coating and PVD coating machine PVD (physical vapor deposition) coating technology is mainly divided into three categories, vacuum evaporation coating, vacuum sputtering and vacuum ion coating. Corresponding to the three categories of PVD technology, the corresponding vacuum coating equipment also includes vacuum evaporation coating machine, vacuum sputtering coating machine and vacuum ion coating machine. In the past ten years, the development of vacuum ion coating technology is the fastest, and it has become one of the most advanced surface treatment methods today. What we usually call PVD coating refers to vacuum ion coating; what we usually call PVD coating machine refers to vacuum ion coating machine.

Vacuum Coater Physical Vapor Deposition

Vacuum coating machine PVD is the abbreviation of English Physical Vapor Deposition, Chinese means "physical vapor deposition", which refers to the thin film preparation technology of depositing materials on the plated workpiece by physical methods under vacuum conditions.

The vacuum coating machine adopts different degassing measures for different workpieces

Usually the workpiece degassing method we use is baking, and the gas and moisture in the workpiece are discharged by heating. Before coating, the workpiece is heated while pumping. Together with the gas in the vacuum chamber, it is pumped out by the vacuum pump.

Different degassing measures are taken for different workpieces to effectively control the emission of gas and moisture inside the workpiece, and improve the stability and uniformity of the coating.
