PVD is the abbreviation of Physical Vapor Deposition (PVD). It refers to the arc discharge technology with low voltage and high current, which evaporates the target material and ionizes the evaporated material and gas by gas discharge under vacuum condition, and makes the evaporated material and its reaction products deposit on the workpiece by the acceleration of electric field.

 

If gradient is to be made, a baffle (MASK) will be added between the target and the workpiece. The thickness of the film deposited in the corresponding position of the large area of MASK is less, and the thickness deposited in the small area of MASK is more.

Because of the different distances, the thickness of the film forming area is different, resulting in different colors (gradient).Gradient color is not difficult, pure green is the most difficult.Medical instrument coating machine Factory
