摘要： 采用先进的表面工程技术对机械零部件表面进行性能强化，不仅能够显著提升其在高速、高载、高温等苛刻工况下的服役安全性和可靠性，还能有效延长其使用寿命。近年来，高熵合金(High-entropy alloys,HEA)因其优异的力学性能、耐腐蚀性和耐高温氧化性，逐渐成为高性能涂层材料的重要研究方向，并被视为传统涂层材料的潜在替代者。特别是在耐磨涂层领域，高熵合金展现出优异的抗磨损能力。高熵合金耐磨涂层的制备工艺方法是近年来的研究热点。基于此，总结了磁控溅射、热喷涂和激光熔覆三种使用广泛的高熵合金涂层制备工艺。阐述了工艺参数优化和添加元素对涂层力学性能的影响。最后，提出多目标优化参数等有待解决的关键问题，并对高熵合金自润滑涂层等方面进行展望。

Abstract: The application of advanced surface engineering technologies for enhancing the performance of mechanical components can significantly improve their service safety and reliability under harsh conditions such as high speed, heavy load, and elevated temperatures while extending their service life. In recent years, high-entropy alloys(HEA) have emerged as a key research focus in high-performance coating materials due to their excellent mechanical properties, corrosion resistance, and high-temperature oxidation resistance. They are increasingly regarded as potential alternatives to traditional coating materials. Particularly in the field of wear-resistant coatings, HEA exhibit outstanding wear resistance. The fabrication methods of HEA wear-resistant coatings have become a research hotspot in recent years. Based on this, three widely used HEA coating preparation techniques are summarized:magnetron sputtering, thermal spraying, and laser cladding. The influence of process parameter optimization and element addition on the mechanical properties of the coatings is also discussed. Finally, key challenges that remain to be addressed, such as multi-objective optimization of process parameters, are highlighted, along with future prospects for HEA self-lubricating coatings.

Key words: high entropy alloys, wear-resistant coating, preparation process, quality optimization
