Abstract In order to improve the performance of Ni based alloy coating 0wt%, 2wt%, 4wt%, 6wt% and 8wt% Al elements were added to Ni based alloy.The effects of Al addition on the wear resistance,high temperature oxidation resistance and thermal fatigue resistance of Ni based alloy were analyzed by SEM, XRD, friction and wear, high temperature oxidation and thermal shock test. The results show that, with the addition of aluminum could significantly improve the cladding formability, but when the aluminum content was more than 4wt%, the cracks appeared. By presetting the Ni based intermediate layer, the content of Al in the coatings could be increased from 4wt% to 8wt% at the premise of no crack defect. The microhardness experiment showed that when the aluminum content was 8wt%, the microhardness of the coating was 740HV, which was 1.85 times of that of the nickel-based coating. The tests of friction and wear showed that the wear resistance of the coating was best at the aluminum content of 6wt% which wear mass loss was 25% of the nickel-based coating. The high temperature oxidation results showed that the oxidation resistance of the coating with 8wt% aluminum content after 850 ℃/120 h oxidation was the best, the Al₂O₃, NiCr₂O₄, (Fe,Cr)₂O₃ and γ-Ni phases formed on the annealed coating, and the oxidation weight gain rate was 1.89 mg/cm², which was only 35% of the nickel-based coating.

Key words： nodular cast iron laser cladding friction and wear high temperature oxidation
