利用离子注入技术可把外来原子直接引入表面层中,这一技术已发展得相当成熟,工业化应用也日渐扩大,但是有关离子注入烧结碳化钨的改性机理研究尚不深入,而且是各国近期研究的重要课题之一。本文报导的是氮离子注入浇结碳化钨对其表面硬度和磨擦学特性的影响,并进而探讨其表面改性机理。 The use of ion implantation technology can be directly introduced into the surface layer of foreign atoms, the technology has been developed quite mature, industrial applications are also growing, but the ion implantation of tungsten carbide modification mechanism is not yet studied, and is the recent study of various countries One of the important topics. This paper reports the effect of nitrogen ion implanted tungsten carbide on its surface hardness and tribological properties, and then discusses its surface modification mechanism.
