Research Progress on Preparation and Corrosion Behavior of High-Entropy Alloy Coatings

High-entropy alloys (HEAs) break the traditional alloy design concept and have a unique solid solution microstructure composed of random arrangement of multiple elements, which makes them have good corrosion resistance. The preparation of high-entropy alloy coatings and their corrosion behavior in high temperature environment and room temperature aqueous solution are reviewed. The effects of environment, alloying elements and processing methods on the corrosion resistance of high-entropy coatings are analyzed, and the development trend and application prospects of high-entropy alloy coatings in the field of corrosion are prospected.
