Wear (erosion/abrasion) and corrosion act in synergy in several industrial installations where corrosive fluids circulate together with a solid phase causing mutual damage. High entropy alloys (HEAs) are promising materials to be used in that type of environments because of their outstanding chemical, electrochemical and mechanical properties. While several review articles are currently available on corrosion, mechanical properties, development of HEAs, microstructure, and HEA coatings, there is an undeniable lack of a comprehensive and critical review focusing on the tribological behaviour and tribocorrosion of bulk HEAs. This work aims to collect, summarise, and critically review the major accomplishments and progresses of HEAs over the last 20 years dealing with wear, corrosion, and wear-corrosion resistance. It highlights the most significant aspects that can influence the performance of HEAs including the change of the base alloying elements, the influence of the temperature, heat treatment, and wear test parameters (load, velocity, duration, distance). Furthermore, operating mechanisms, together with the relationship between microstructure and wear resistance, and between microstructure and corrosion resistance will be described. Finally, the articles that have been reported in the literature dealing with tribocorrosion of HEAs will be reviewed. The results of this study are expected to guide potential researchers and provide them with the sum of current trends in HEAs in terms of corrosion resistance, wear resistance and the synergy of both, in the hope of helping them to make the right decision to design and develop new HEAs or improve the research on the existing ones.
在一些工业装置中，磨损（侵蚀/磨蚀）和腐蚀协同作用，在这些装置中，腐蚀性流体与固相一起循环，造成相互损害。高熵合金（HEA）因其优异的化学、电化学和机械性能，有望用于这类环境。虽然目前有几篇关于高熵合金的腐蚀、机械性能、发展、微观结构和高熵合金涂层的综述文章，但不可否认的是，缺乏一篇全面且批判性的综述，聚焦于块状高熵合金的摩擦学行为和摩擦腐蚀。这项工作旨在收集、总结和批判性地回顾高熵合金在过去20年中在磨损、腐蚀和耐磨蚀方面取得的主要成就和进展。它突出了可能影响高熵合金性能的最重要方面，包括基础合金元素的变化、温度、热处理和磨损试验参数（载荷、速度、持续时间、距离）的影响。此外，还将描述运行机制，以及微观结构与耐磨性之间、微观结构与耐腐蚀性之间的关系。最后，将对文献中报道的有关高熵合金摩擦腐蚀的文章进行综述。本研究结果有望为潜在的研究人员提供指导，并向他们提供高熵合金在耐腐蚀性、耐磨性以及两者协同作用方面的当前趋势总结，希望帮助他们做出正确的决策，以设计和开发新的高熵合金，或改进对现有高熵合金的研究。
