Abstract The effects of laser power on the microstructure and wear-resistant and corrosion-resistant properties of Ni-based alloy cladding coatings were studied in this paper, in order to get the optimal laser power parameters and obtain Ni-based alloy coatings with good metallurgical bonding and excellent wear resistance and corrosion resistance. The results showed that Ni-based alloy coating prepared by laser cladding is metallurgically bonded to the substrate without obvious cracks and holes, and the main composition of the Ni-based alloy coating is γ-(Ni,Fe) solid solution, and a small amount of Cr3C7 phase appeared in relatively lower power. With increasing laser powers, the element contents of Ni and Cr in the cladding layers decreased, the element content of Fe in the cladding layers increased, and the thickness of cladding layers increased from 545 μm to 1 100 μm, microstructure was coarsened obviously and the transition from dendrites to cellular dendrites tendency. Meanwhile, with increasing laser powers, the microhardness decreased from 508 HV to 375 HV, and the wear resistance of the specimens decreased, but the anti-corrosion resistance was enhanced, the corrosion current density decreased from 4.347×10-7 A/cm2 to 8.257×10-8 A/cm2.
