摘　　要：实验采用高性能铅锡青铜合金ZCu Pb20Sn5研究了浇注温度和钢基体预热温度对钢铜双金属界面结合强度的影响。实验结果表明,在铅锡青铜熔炼温度为1 200℃,钢基体预热温度为1 200℃时,钢铜双金属界面剪切强度达到142 MPa。The influences of pouring temperature and the steel substrate preheating temperature on the bimetallic interface bonding strength of copper and steel were investigated adopting the high-performance leaded-tin bronze ZCu Pb20Sn5 alloy.The results show that the bimetallic interface shearing strength of copper and steel reaches 142 MPa when the bronze smelting temperature is 1 200 ℃ and the steel substrate preheating temperature is 1 200 ℃.
