摘要:
水力发电装备和海洋装备中的过流部件在服役时不仅受到腐蚀的影响，还同时受到空蚀破坏，导致过流部件表面材料损失甚至发生断裂，进而严重降低装备服役安全和寿命。现有的过流部件应用材料大多数为铜合金和不锈钢，存在耐腐蚀性能和力学性能都无法同步提升的瓶颈，开发出符合“高性能、长寿命、高可靠性”且环境适应性强的新型抗空蚀-腐蚀材料成为当前的研究热点。多主元合金独特的四大效应赋予其成为极端环境领域中抗空蚀-腐蚀材料的天然优势，其广泛可调的微观组织、优异的力学性能、出色的抗氧化性以及卓越的耐腐蚀性能，为开发新型抗空蚀-腐蚀材料提供了坚实的研究基础。抗空蚀-腐蚀多主元合金材料可以通过涂层和块体两个方面制备，同时可以按照主元种类和成分调控、合金化以及形成多主元复合材料来提高抗空蚀-腐蚀性能。综述了多主元合金作为抗空蚀-腐蚀材料的研究进展，重点从材料的微观结构出发，详细讨论了不同涂层和块体多主元合金在空蚀-腐蚀性能方面的表现及其影响因素。
Abstract:
In hydroelectric and marine equipment, flow components are not only susceptible to corrosion during operation but also subject to cavitation damage. This results in material loss on the surface of the flow components and even fractures, significantly reducing the safety and lifespan of the equipment. Currently, most materials used for flow components are copper alloys and stainless steel, which face the challenge of failing to simultaneously improve corrosion resistance and mechanical properties. Developing new anti-cavitation erosion-corrosion (anti-CE-C) materials that meet the requirements of “high performance, long life, high reliability” and strong environmental adaptability has become a major research focus. The unique four major effects of multi-principal element alloys (MPEAs) provide them a natural advantage as anti-CE-C materials. The four unique major effects of MPEAs give them a natural advantage as anti-CE-C materials in extreme environments. Their highly adjustable microstructures, exceptional mechanical properties, outstanding oxidation resistance, and superior corrosion resistance lay a strong foundation for the development of new anti-CE-C materials. Their anti-CE-C performance can be enhanced through the regulation of principal element types and compositions, alloying, and the formation of MPEA composites. This review highlights the research progress on MPEAs as anti-CE-C materials, with a focus on their microstructure. It offers a comprehensive discussion of the CE-C performance and the factors influencing this behavior in both coatings and bulk MPEAs.
