国外从1972年起开始研究开发PVD技术,到1980年逐步应用于刀具表面强化。现在已广泛应用于机械、电子、电工、光学、航空航天、化工、轻工及食品工业等各个部门。不仅沉积各类金属与不同组分的合金,还能沉积多种化合物。不仅能在金属上沉积而且在陶瓷、玻璃、塑料等非金属上也
Abroad from 1972 onwards began to research and development of PVD technology, gradually applied to the 1980 tool surface hardening. Has now been widely used in machinery, electronics, electrical, optical, aerospace, chemical, light industry and food industries and other departments. Not only the deposition of various types of metals and alloys of different components, but also deposited a variety of compounds. Not only in metal deposition but also in ceramics, glass, plastic and other non-metallic also
