摘要：

High-entropy alloy ( HEA) coatings with high thermal stability and high temperature resistance of HEA coatings show a new attraction in the field of high temperature coating. The method of preparing HEA coating(HEAc) by laser cladding technology is one of the best preparation methods which can achieve superior performance. The latest research results of HEAc prepared by laser cladding technology were summarized from the view of component design, microstructure, annealing process and properties, high temperature oxidation resistance and other properties. The problems existing in the preparation of HEAc by laser cladding technology were analyzed. It was put forward that the scientific research system should be perfected from the aspects of component design, basic theory, performance law and processing technology in the future. The high-entropy alloy coatings with excellent performance are expected to be prepared.
