摘要
研究了激光焊接条件下ＳｉＣｗ／６０６１Ａｌ铝基复合材料的界面反应，探讨了激光输出功率、激光脉冲频率等焊接工艺参数对该材料界面反应的影响。结果表明：激光焊接条件下ＳｉＣｗ／６０６１Ａｌ铝基复合材料可焊性差的原因主要是与基体６０６１Ａｌ铝合金和增强相ＳｉＣ晶须间的界面反应Ａｌ（ｌ）＋ＳｉＣ（ｓ）→Ａｌ４Ｃ３（ｓ）＋Ｓｉ（ｓ）有关，激光输出功率是影响界面反应程度的主要焊接工艺参数。在此基础上成功实现了ＳｉＣｗ／６０６１Ａｌ铝基复合材料的激光焊接。
Interface reaction of aluminium
matrix composite SiC/6061Al in the welded joint subjected to laser welding was studied Effects
of laser output power and pulse frequency welding parameters on interface reaction were also
investigated The results show that main reason for bad weldability of the composite concernes
with interface reaction during the welding,that is:4Al(l)+3SiC(s) → Al 4C 3(s)+Si(s) The study
proves that the laser welding can be successfully used in the welding of SiC w/6061Al
