| Abstract: | The effect of Al2O3 on the wear resistance of laser cladding nickel-based alloy coating is investigated. Through the results of mierostructure observations, hardness test and wear test it shows that the addition of Al2O3 can modify the microstructure and properties of laser cladding coating. The mierostructure gets refined and wear resistance are conspicuously improved. |
