Research progress of high entropy alloys, including design concept, synthesis methods and the main properties, are summarized in this paper. The properties of metal coating, compound coating and composite coating are reviewed. HEA coatings present different properties from traditional coatings, especially in the strength, hardness,high temperature stability, wear and corrosion resistance, which have important academic research value and potential application in instruments, cutting tools and moulds.
