锆及其合金具有比强度高、密度小、吸收热中子面积小和耐腐蚀性能良好等优点,已被应用于航空航天、核工业和航海等特殊领域。然而由于锆合金通常作为结构部件应用于高温、高压、高强度等苛刻的服役环境中,因发生摩擦磨损而限制了其工业化应用。本文综述了近年来锆合金摩擦磨损性能优化的研究进展,介绍了锆合金的摩擦磨损行为及机制,总结了摩擦磨损实验中速度、载荷以及温度对锆合金摩擦磨损性能的影响,概括了表面处理、合金化以及热处理等可改善锆合金耐磨性能的有效方法。最后,对未来抗耐磨性锆合金的研究发展和应用进行了总结和展望。

Zirconium and its alloys have the advantages of high specific strength, low density, small thermal neutron absorption area and good corrosion resistance. They have been used in special fields such as aerospace, nuclear industry and navigation etc. However, because zirconium alloys are usually used as structural parts in harsh service environments such as high temperature, high pressure and high strength, the friction and wear phenomena of zirconium alloys has limited its industrial applications. In this paper, the research progress on the optimization of friction and wear properties of zirconium alloys in recent years was reviewed. The friction and wear behavior and mechanism of zirconium alloys was introduced. The effects of speed, load and temperature on the friction and wear properties of zirconium alloys in friction and wear experiments were summarized. The effective methods to improve the wear properties of zirconium alloys such as surface treatment, alloying and heat treatment were summarized. Finally, the research development and application of wear-resistant zirconium alloys in the future were summarized and prospected.
