摘要
通过与基体铝合金的对比试验研究了颗粒增强铝基复合材料Ａｌ２Ｏ３ｐ／６０６１Ａｌ扩散焊各主要工艺参数对接头强度的影响规律，探讨了接头区域微观组织状态对接头强度的影响。结果表明：焊接温度是影响接头强度的主要工艺参数，接头区域存在氧化物及增强相偏聚等缺陷，是造成该种材料焊接性差的主要原因，在此基础上成功实现了颗粒增强铝基复合材料Ａｌ２Ｏ３ｐ／６０６１Ａｌ的扩散连接。
Effects of individual main parameter of diffusion welding Al 2O 3P /6061Al on the strength of joint were studied by comparing with aluminum base alloy, and the relationship between microstructure and strength of joint were also investigated. The results show that key parameter affecting joint strength is welding temperature. Main reason for poor weldablity of Al 2O 3P /6061Al Composite is attributed to the defects such as oxide film and reinforcement segregation in the welded joint. On the basis of this, diffusion welding of aluminum matrix composites reinforced with particle was successfully realized.
