Abstract:

一种镁合金中温钎焊材料属于镁合金焊接连接技术领域。现有镁合金钎焊材料大多存在工艺性不好或接头性能差等技术问题。本发明镁合金中温钎焊材料的成分质量百分含量范围如下:Al1~2.5%,Zn46~52%,余量为Mg。钎料采用熔剂保护法熔炼,采用机械分割、精密铸造、气体保护球磨法可得到块状、条状、粉末状等形式的钎料。该钎料的熔化温度范围为336~361℃,钎焊温度低,为380~400℃,可适应于固相线温度在400℃以上的镁合金的钎焊。本发明钎料具有优良的钎焊特性,在钎焊温度下,铺展性和间隙填充性良好。适合的钎焊方法包括保护气氛钎焊、感应钎焊、炉中钎焊等。该钎料钎焊AZ31B镁合金接头剪切强度大于52MPa,接头抗拉强度大于72MPa。
