钛及钛合金的表面渗氧强化技术

Surface Oxygen Diffusion Hardening Technology of Titanium and Titanium Alloy

钛及钛合金具有比强度高、耐蚀性好、良好的高温性及生物相容性等优点,是新兴的结构和功能材料,但由于其表面耐疲劳和耐磨损性能差等缺点使其应用受到限制。表面渗氧强化技术是提高钛合金表面性能的一种有效手段,本文综合评述了表面渗氧技术在钛及钛合金中的应用现状及研究进展。

Titanium and titanium alloys have many advantages including high specific strength, good corrosion resist- ance, high thermal stability and good biocompatibility and so on, are new structure and function materials, While the practical application is restricted due to its shortcomings such as low hardness, poor wear resistance and fatigability. Sur- face oxygen diffusion hardening technology is an effective means to improve the surface performance of titanium and titani- um alloy. The application situation and research prospects of surface oxygen diffusion hardening technology for titanium and titanium alloys are summarized in this paper.
