Introducing emerging high entropy alloys materials into advanced intelligent manufacturing for laser additive repair is expected to promote the deep integration of new generation of materials and manufacturing technology and greatly improve the utilization of raw materials and energy,which have broad application fields and excellent development prospects. This paper introduces the application status of high entropy alloys in laser additive repair,and points out that the mismatch of strength and toughness,inaccurate performance control and unclear strengthening mechanism are the key scientific problems that need to be solved urgently in the expansion and application of high entropy alloys in laser additive repair. Exploring the ductile-brittle transition mechanism of the high entropy alloys cladding coating metal,clarifying the basic mapping relationship among the materials,processes,microstructure and coating performance of cladding coatings,obtaining a complete and effective method for predicting the composition of high entropy alloys,innovating the design of alloy powder system,optimizing and adjusting the control processes,and obtaining a high-performance cladding coating suitable for extreme service environment and with low cost are the main research focus and development trends in the future.
