摘要
磨损是机械失效的一种普遍形式,约占据机械零件失效的80%。摩擦磨损不仅增加了原料和能源的损耗,而且无法保证机械零件的安全可靠性。高熵合金由于其特殊的四大效应,使得它成为近年来有别于传统合金材料领域的研究热点,通过调整高熵合金元素种类及配比、选择合适的制造方法和热处理工艺可以在一定程度上减缓磨损速率、降低磨损量,起到提高耐磨性能的效果。归纳了耐磨高熵合金的类别,讨论了不同元素及配比对块体高熵合金磨损性能的影响,总结了采用不同制造方法、热处理工艺及表面化学改性制备的高熵合金的耐磨性能差异。最后,结合高熵合金在摩擦磨损方面的现状及存在的问题,对未来高熵合金在耐磨金属材料领域的研究进行了展望。
Wear is a common form of mechanical failure,accounting for roughly 80%of mechanical parts failure.Friction and wear not only increase the loss of raw materials and energy,but also jeopardize the safety and reliability of mechanical parts.High entropy alloy,unlike traditional alloy materials,has become a research hotspot in recent years due to its special four effects.The wear rate and amount can be reduced to some extent by adjusting the types and proportions of high entropy alloy elements,as well as selecting appropriate manufacturing methods and heat treatment processes.The categories of wear resistant high entropy alloys were summarized,the effects of different elements and element ratios on the wear properties of high entropy alloys were discussed,and the wear resistance differences of high entropy alloys prepared by different manufacturing methods were summarized.Finally,the future research of high entropy alloys in the field of wear-resistant metal materials was anticipated,in conjunction with the current situation and existing problems of high entropy alloys in friction and wear.
