前言自从1961年苏联推出了第一台等离子涂层设备以来,等离子涂层被广泛地用于各种不同类型的高速钢刀具和硬质合金刀具。等离子TiN涂层工艺的出现,被认为是高速钢的一次革命。1986年西方国家每年大约有两千万件高速钢刀具采用了PVD涂层,在硬质合金刀具上的应用数量亦在增长。目前国内一些工具厂和量具刃具厂等均已从国外 Introduction Plasma coatings have been widely used in a variety of different types of HSS and carbide tools since the Soviet Union launched its first plasma coating facility in 1961. The emergence of plasma TiN coating process, is considered a revolution in high-speed steel. In 1986, about 20 million high-speed steel knives were coated with PVD coating in western countries each year, and the number of applications in cemented carbide knives also increased. At present, some domestic tool factory and measuring tool factory have been from abroad
