摘　　要：锡青铜是磨损件的一种基础材料,在工业领域应用广泛。分析CuSn12Ni2锡青铜的金相组织、能谱,应用高速激光熔覆工艺将CuSn12Ni2锡青铜粉末熔覆在42CrMo合金钢基体上,进行结合强度试验。研究结果表明,CuSn12Ni2锡青铜与42CrMo合金钢基体间达到了冶金结合。Tin bronze is a basic material for wear part and is widely used in the industrial field.The metallographic structure and energy spectrum of CuSn12Ni2 tin bronze were analyzed,and CuSn12Ni2 tin bronze powder was cladded on the 42CrMo alloy steel matrix by high-speed laser cladding process for bonding strength test.The findings show that the metallurgical bonding between CuSn12Ni2 tin bronze and 42CrMo alloy steel matrix has been achieved.
