Abstract: Laser cladding has the advantages of fast heating and cooling rates, high bonding strength between the coating and substrate, low dilution rate, and wide applicability of the process. High entropy alloys are widely applied in laser cladding due to their exceptional comprehensive properties, which stems from four core characteristic effects: the high entropy effect in thermodynamics, lattice distortion effect in structure, sluggish diffusion effect in kinetics, and the "cocktail" effect in performance. The latest developments in laser cladded high entropy alloy coatings are systematically reviewed. The optimization of laser processing parameters can effectively influence microstructures and properties, thereby enhancing the coating formation quality. Auxiliary processes such as heat treatment, ultrasonic vibration and magnetic field assistance can effectively suppress porosity and cracks. Adding hard ceramic phases and rare earth elements can significantly enhance the hardness, wear resistance, and corrosion resistance of coatings. Alloy composition design progressively evolves from equimolar ratios to non-equimolar configurations. Finally, in order to address the current limitations in theoretical prediction and simulation of laser cladded HEA coatings, the future research directions emphasizing intelligent approaches (machine learning, digital twins) and extreme environment applications were proposed.
