摘要
应用惯性径向摩擦焊工艺进行了35CrMnSi/T3的摩擦焊接,并利用扫描电子显微镜观察了界面的微观结合特征,利用能谱分析仪检测了界面元素的扩散.试验结果表明:惯性径向摩擦焊飞轮转速为3 000 r/min时,35CrMnSi/T3接触面结合紧密并形成了明显的波浪状"咬合",界面附近发生了元素的互相扩散与溶解,实现了冶金结合;界面处Fe原子在Cu基体中的扩散距离约为33μm,Cu原子在钢中的扩散距离约为3μm;径向摩擦焊接过程中接触面快速而剧烈的塑性变形有利于抑制摩擦焊接头中氧的不利影响.
Inertial radial friction welding process was adopted to weld 35CrMnSi and T3.The interface microcosmic binding characteristics were observed by SEM.The element diffusion near the interface was detected by EDS.The results show the tightly connected contact surface of 35CrMnSi/T3 with obviously wavy occlusion at flywheel rotation speed of 3 000 r/min.The elements diffusion and dissolution through the interface occur,and the metallurgical bonding forms.The diffusion distance of Fe atoms into copper matrix gets to 33 μm and Cu atoms into Fe matrix about 3 μm.In addition,the adverse effect of oxygen on friction welded joints is inhibited by the evident plastic deformation of the contact surfaces in radial friction welding process.
