<p>In order to achieve surface repair and strengthening of molds, the effects of aluminum and vanadium content on the micro-mechanism and properties of Al_xV_yCrMnFeCoNi high-entropy alloy coatings were investigated. Al_xV_yCrMnFeCoNi (x = 0,0.5,1.0,1.5; y=0,0.5,1.0,1.5) high-entropy alloy coatings were prepared on the surface of H13 steel using laser cladding technology, and the effects of different aluminum and vanadium contents on the phase composition, microstructure, microhardness and wear of the coatings were analyzed. In the study of laser melting cladding of Al_xV_yCrMnFeCoNi series of high-entropy alloy coatings, the addition of V element caused the BCC solid solution phase (110) peak of Al_1.0V_yCrMnFeCoNi to move to a lower diffraction angle, leading to the generation of a lattice aberration corresponding to an increase in the lattice constant, which altered the pristine phase composition of the coatings, transformed dendritic crystals into isotropic crystals and generated needle-like and striated CrV phases. When the molar ratio of Al is 0.5 and 1.0, due to the CrV phase can enhance the hardness of the coating, wear resistance increases with the increase in V content; when the molar ratio of Al is 1.5, due to the increase of defects and aberrations in the coating, wear resistance decreases with the increase in V content. The corrosion resistance of Al_1.0V_yCrMnFeCoNi high-entropy alloy coatings increases first and then decreases with the increase in V content.</p>
