新型铜基涂药钎料研究

Reserch on new copper matrix brazing

以铜基涂料H68、H62为基本钎料,以脱水硼砂为钎剂,采用电阻钎焊的方法,在研究了添加在钎剂中的Zn粉、Mn粉对钎焊接头性能的影响,得出采用该方法可以对钎缝进行合金化处理,提高钎焊接头性能结论的基础上,在钎剂中添加Zn、Mn和CeCl3粉末,对钎缝作正交试验研究,得出钎焊接头剪切强度最高时钎剂中添加Zn、Mn和CeCl3粉末的最佳配方。

This paper researched the effects of Zinc and Manganese powder on the properties of brazing weld point. In this experiment, the H68 and the H62 were used as basic brazing material and the dehydrated borax as brazing agent, at the same time, resistant welding was employed. Through the studying, we knew that, we can make the welding point alloyed by this way. As a result, the strength of welding point has been increased. At last, we gained the best ingredients of Zn, Mn and CeCl3 when the shear strength of welding point reached the top.
