An all-around way to analyze the corrosion behavior and the potential applications of high-entropy alloys coating

High-entropy alloys (HEAs) are an advanced material that has attracted people's attention in recent years due to their uniform structure and excellent mechanical properties. Therefore, thanks to their excellent performance, the alloys and their coatings are widely used in various industrial sectors. Moreover, HEAs can suffer from certain corrosion during actual use, which can negatively impact their properties and working life. The research status and progress of corrosion behavior in HEAs are reviewed in this paper. First, we made an introduction to the basic concepts, characteristics, and preparation processes of HEAs. Then, a detailed analysis and discussion are made for the corrosion behavior, corrosion mechanism and influencing factors of HEAs. These factors mainly include fabrication processing, the addition of alloying elements, element recombination, and alloy structure. Finally, the future research direction and development of corrosion, as well as their potential applications of HEAs are concluded and prospected. Consequently, based on the summary of this research progress, it can provide valuable technical guidance and references for junior researchers who are just starting out, as well as for engineering and technical personnel in related fields. And it also plays an enlightening role in promoting the design of new research programs and the development of new production processes.
