摘要：

The orthogonal test of laser cladding of Stellite6 coating on the 42CrMo alloy surface with single-pass is carried out and the influences of laser power, scanning speed, powder feeding rate and spot diameter on the dilution rate and microhardness of cladding layers as well as the interactive action among the main influencing factors arc analyzed. The results show that the laser power has the most significant influence on the dilution rate of cladding layer, while the scanning speed has the most obvious influence on the microhardness of cladding layer. The optimal process parameter combination is laser power of 1100 W, scanning speed of 8 mm.s(-1), powder feeding rate of 1.2- 1.4 rad.min(-1) and spot diameter of 3.7 mm from the comprehensive analysis of the dilution rate and microhardness of cladding layers.
