Abstract:: Thermal spraying coating technology has developed rapidly in recent years,and has become an irreplaceable material surface modification technology in the field of surface engineering, and plays a key role in many industrial applications. As a new metal material, high entropy alloys have a unique composition design and microstructure, which exhibits more excellent performance than traditional materials. It has deep academic research value and the industrial application potential in thermal spraying high-performance coatings. The work summarized the advance of high entropy alloy coatings in recent years. Firstly, the definition and characteristics of high entropy alloys were briefly introduced. Based on the technical principles and characteristics of different thermal spraying technologies, the relevant researches on the preparation of high entropy alloy coatings were described. Spraying is one of the common methods on preparing high entropy alloy coatings, including plasma spraying, supersonic flame spraying, cold spraying and high-velocity arc spraying. The research progress on thermal spraying high entropy alloy coatings microstructure (porosity, phase composition), performance (hardness, wear resistance, corrosion resistance) and other aspects were summarized in detail. And the future development direction of thermal spraying high entropy alloy coatings was prospected. With the characteristics of thermal spraying technology and the performance advantages of high entropy alloys, thermal spraying high entropy alloy coatings have huge industrial application potential. The current material system of thermal spraying high entropy alloy coatings is limited, and the design of the material system of thermal spraying high entropy alloy coating based on simulation calculation and machine learning technology will play an important role. In addition, exploring the coatings preparation process, post-treatment process and performance evaluation mechanism is of great significance to improve the thermal spraying high entropy alloy coating performance.
