摘　　要：在材料表面制备高熵合金涂层,可显著提升其表面硬度、力学性能和摩擦磨损性能,延长服役寿命。高熵合金涂层在对基体材料抗磨性要求较为苛刻的领域表现出巨大的应用潜力,然而鲜有相关综述论文,有必要对目前关于高熵合金涂层耐磨性的研究成果进行评述。根据材料科学与工程四面体可得,合金成分是影响高熵合金涂层耐磨性的根本原因。对现有研究梳理,归纳总结Al、Ti、Cu、Co、Nb、Mo、W等金属系元素,Si、B、C、O非金属系元素、元素的复合作用,以及TiC与WC等陶瓷颗粒对高熵合金涂层微观组织、硬度和耐磨性机理的影响。结果表明,通过微量或大量掺杂合金成分可以改变高熵合金涂层的组织结构及其强化机制,进而改善其耐磨性能。最后,指出目前研究工作中所面临的挑战,展望高熵合金涂层的应用前景和发展方向。系统地概括目前合金成分对高熵合金涂层耐磨性影响的相关研究,研究结果对于制定更科学合理的耐磨性设计方案、提高涂层的耐用性和实际应用效果有着积极的作用,对相关领域研究有着一定的参考价值。Frictional wear occurs primarily on the surface of materials,and the failure of most mechanical components is due to the resulting surface wear,which not only reduces their reliability and safety,but is typically unavoidable in most mechanical systems with moving parts.The durability and reliability of engineering components are closely related to their wear resistance.The development of advanced materials to reduce the energy and material losses in moving mechanical systems remains a significant challenge.Novel high-entropy alloys composed of multiple principal elements offer promising prospects for the development of materials with excellent wear resistance owing to their superior hardness,outstanding wear resistance,and excellent corrosion resistance.However,the preparation cost of block high-entropy alloys is high,and high-entropy alloy films are difficult to apply in practical situations.Therefore,high-entropy alloy coatings have become a popular research topic.By preparing high-entropy alloy coatings on the surface of materials,the surface hardness,mechanical properties,friction,and wear properties can be significantly improved,thus extending the service life.High-entropy alloy coatings have shown enormous potential for applications in areas where the wear resistance of the base material is more demanding;however,there are few relevant review papers.Hence,it is necessary to review current research results on the wear resistance of high-entropy alloy coatings.It is imperative to review the current research results on the wear resistance of high-entropy alloy coatings.Additionally,it is of utmost significance to understand the research progress in improving the wear resistance of high-entropy alloy coatings and to facilitate their applications in industry.According to the materials science and engineering tetrahedron,it can be concluded that the microstructure,heat treatment method,temperature,cooling method,holding time,preparation process,processing process,and whether a protective oxide layer is produced d
