摘　　要：CoCrFeNi系高熵合金涂层具有优良的耐腐蚀性、塑韧性和耐高温氧化性,但由于强度低、硬度和耐磨性差等问题,其工程应用受到限制。目前已有研究表明,添加元素可以改善其性能。分析并总结了不同元素对CoCrFeNi系高熵合金涂层组织结构的影响,指出了CoCrFeNi系高熵合金涂层研究中存在的技术问题,并对其发展进行了展望。CoCrFeNi series high-entropy alloy coatings exhibit excellent corrosion resistance, plastic toughness, and high-temperature oxidation resistance, while the engineering applications are limited due to low strength, poor hardness and wear resistance. At present, a large number of experimental results reveal that addition of elements can improve the performance of the HEAs. Effects of various elements on microstructure and properties of CoCrFeNi series high-entropy alloy coatings were reviewed. The technical problems existing in the investigation were proposed, and future research directions were prospected.
