摘　　要：根据原子扩散理论对AZ31B镁合金与不锈钢0Cr18Ni9进行了扩散连接工艺研究。利用CVI-10型扩散设备对AZ31B镁合金与不锈钢0Cr18Ni9进行了在不同连接温度条件下的扩散连接。利用金相显微镜、扫描电镜、能谱分析仪器等对扩散连接接头组织及连接界面元素成分进行了分析,测试了接头的剪切强度。结果表明:AZ31B镁合金与不锈钢0Cr18Ni9的扩散连接最佳温度为450℃,接头界面存在元素的扩散,界面存在微裂纹。Abstract： Research on diffusion bonding process of AZ31B magnesium alloy and 0Crl 8Ni9 stainless steel was carried according to atomic diffusion theory. CVI-10 diffusion bonding machine was used on the AZ31B magnesium alloy and 0Crl 8Ni9 stainless steel at different temperature conditions. Investigation of diffusion bonding joints morphology and in- terface elements were carded out by optical microscope, scanning electron microscopy and electron probe micro analysis, and sheafing strength was tested. The result is that the best temperature of AZ31B and 0Cr18Ni9 diffusion bonding is 450 ℃ ,there are segregation, joints micro-cracks.
