摘　　要： 总结了近年来双层辉光离子渗金属技术的发展,介绍了以双辉工艺在钛及钛合金表面形成阻燃合金,采用无氢渗碳在钛及钛合金表面形成高硬抗磨层,在纯铁、碳钢等基材表面形成时效硬化高速钢,在纯铜表面形成Ti-Cu耐磨合金等表面冶金新技术。 This paper summarises some new development of the double glow plasma surface metallurgy technology in the last few years: Ti-Cu and Ti-Cr burn-resistant alloys have been produced on the surfaces of titanium and titanium alloy Ti6Al4V. Co-W-Mo-Fe age-hardened high speed steel and high Cr alloy have been formed on the surface of carbon steels. Ti-Cu wear-resistant alloy was also produced on the surface of pure copper. By using this process and solid graphite as carbon source, hydrogen-free carburising has been achieved in order to avoid hydrogen embrittlement of titanium. The experimental results indicate that the double glow plasma surface metallurgy is an advanced and powerful method for surface alloying.
