| Abstract: | Bond strength of laser cladding of Fe-base alloy coating to Al-Si alloy substrate was measured by tensile stage of SEM.The influence preheating temperature of substrate upon interface bond strength was discussed,and the process of cracks formation and developing for laser cladding interface were also studied.The results indicate that the method can accurately measure the bond strength of laser cladding. |
