Environmental corrosion inevitably occurs during the use of alloys, making their corrosion resistance a special requirement for their application under specific conditions. The environmental corrosion behavior of alloys, seawater corrosion behavior, corrosion resistance, and microstructure of high-entropy alloys (HEAs) have been prominent research topics over the past decade, all of which warrant further investigation. The corrosion resistance and passivation film strength of HEAs could be enhanced by improving their microstructure with appropriate adjustments of their elemental composition and content. In this review, the research status and corrosion mechanism of HEAs in seawater solutions with NaCl as the main component were examined. Moreover, the correlation between the microstructure, elemental composition, and corrosion resistance of HEAs was revealed.

高熵合金的耐腐蚀性能及机理：综述

合金在使用过程中不可避免地会发生环境腐蚀，使其耐腐蚀性能成为其在特定条件下使用的特殊要求。合金的环境腐蚀行为、海水腐蚀行为、高熵合金（HEA）的耐腐蚀性和微观结构一直是过去十年的重要研究课题，所有这些都值得进一步研究。通过适当调整元素组成和含量来改善其微观结构，可以提高HEA的耐腐蚀性和钝化膜强度。本文综述了HEA在以NaCl为主要成分的海水溶液中的研究现状和腐蚀机理。此外，还揭示了 HEA 的微观结构、元素组成和耐腐蚀性之间的相关性。
