钛合金微动磨损的研究进展

Research Advances in Fretting Wear of Titanium Alloys

钛合金耐磨性能较差,对微动磨损十分敏感,使其应用和发展受到了一定的限制。为此,总结了钛合金微动磨损性能的影响因素,综述了钛合金抗微动损伤方法的研究进展。目前,关于钛合金微动磨损的研究主要存在两方面的局限性:①对于钛合金微动磨损的研究大多是在单一影响因素及稳定参数下进行的;②缺乏关于钛合金在特殊工况下微动磨损的研究。因此,未来对于钛合金微动磨损的研究应多结合工业应用中微动磨损的失效实例,加强多因素、变参数以及特殊工况下的微动磨损研究;在掌握微动磨损失效机理的基础上,根据钛合金的特性,探索新型表面处理技术,进一步改善钛合金微动磨损失效问题。

Titanium alloys have poor wear resistance and are especially sensitive to fretting wear,which limit their application and development.Therefore,the influence factors of fretting wear properties and the research progress of fretting wear resistance of titanium alloys are reviewed.At present,there are two limitations in the research of fretting wear of titanium alloys:①the research on fretting wear of titanium alloys is mostly carried out under the single and stable impact parameters;②lack of research on fretting wear of titanium alloys under special working conditions.Thus,the future research on fretting wear of titanium alloys should be combined with the failure examples in industrial applications.Besides,the research on fretting wear under multi factors,variable parameters and special working conditions should be reinforced.On the basis of fretting wear failure mechanism,according to the characteristics of titanium alloys,composite surface treatment technology would be further studied to significantly improve the fretting wear performance of titanium alloys.
