摘要
本文采用添加Ti的Ag-Cu-Zn合金作为钎料,适当控制钎焊工艺,实现了金刚石与钢基体的高强度连接,采用扫描电镜和能谱仪对金刚石与钎料界面进行了分析,分析结果表明:Ti在界面处有聚积并与C生成化合物。为验证钎焊工具的性能,分别进行单颗磨粒磨损试验和套料钻钻孔试验,单颗磨粒磨损试验中,单颗磨粒在重负荷工作条件下,仍有正常磨耗的过程。套料钻钻500个孔时磨粒无明显磨损,说明采用添加Ti的Ag-Cu-Zn合金做钎料钎焊后,金刚石仍能保持良好的耐磨性能。
The high-strength bonding between diamond grits and steel matrix was realized by using alloy Ag - Cu - Zn ＋ Ti filler under controlled brazing technology was analyzed by scanning electron microscope （SEM） showed that Ti accumulated on the diamond＇ s surface, in this paper. The interface between alloy and diamond and energy dispersion spectrometer （EDS）. Results and also formed compound with C. Aiming for verifying the performance of brazed diamond tool, single diamond grit abrasion test and tool drilling test were conducted. Single diamond grit appeared normal abrasion process under heavy duty test, and the diamond grits wear is not obvious after drilling 500 holes, which show that the wear resistance of brazed diamonds can keep their original excellent properties.
