PVD (physical vapor deposition) or physical vapor deposition is widely used on the current international advanced surface treatment technology.
即物理气相沉积，是当前国际上广泛应用的先进的表面处理技术。

It has a fast deposition rate and surface cleaning features, in particular strong adhesion with the film, diffraction, and can be coated material widely and so on.
它具有沉积速度快和表面清洁的特点，特别具有膜层附着力强、绕射性好、可镀材料广泛等优点。

Electroplating: use the principle of electrolysis, the metal and alloy parts deposition in the surface, form even, density, good adhesion of the metal layer process.
