以SiCW/6061Al铝基复合材料为对象， 通过系列试验研究了激光焊接条件下铝基复合材料的界面行为， 指出该种材料可焊性差的原因主要是与焊接过程中Al(l)+SiC(s)→Al4C3(s)+Si(s)的界面反应有关。 研究了焊接工艺参数对界面反应的影响， 探索出铝基复合材料熔焊的新途径。
Interface reaction of aluminium matrix composite SiCw/6061Al in the welded joint subjected to laser welding was studied. Through a series of tests, it was pointed out that the main reason for bad weldability of the material is concerned with the interface reaction taking place during the welding, that is: 4Al(l)+3SiC(s)→Al4C3(s)+Si(s). Effects of welding parameters on interface reaction were also investigated. A new method for welding of aluminium matrix composite by fusion welding was probed.
