摘要：

In this paper, the effects of laser power, spot diameter, and scanning speed on the performance of laser cladding NiCrBSi alloy coating on 42CrMo steel substrate were studied, and nine orthogonal experiments were designed for experiment. The experimental data of OM morphology, microstructure, microhardness and wear property of coating were analyzed by using the methods of visual analysis and range analysis. The results show that laser power is the main factor affecting the height of the cladding coating. The spot diameter has the largest effect on the width of the cladding coating. The scanning speed has a significant effect on the depth of the molten pool. The laser power has the greatest influence on the microhardness and wear resistance of the cladding coating. As the laser power increases, the microhardness of the cladding coating decreases. The wear forms of the cladding coating are mainly abrasive and adhesive wear.
