| 摘 要： | 钎焊是刀具制作过程中的重要环节,焊接质量直接影响刀具连接强度。通过在真空环境中加热,以YG8硬质合金和PCD复合片为焊接母材进行钎焊试验。对比3种钎料在不同焊接温度和保温时间下钎料润湿性和焊接强度的变化,确定3种钎料的最佳焊接参数及适用范围,并分析了阻流剂的使用对钎料阻流的效果,试验表明,使用阻流剂能有效控制钎料溢流至非焊接面。

| Abstract: | Brazing is a very important procedure in the process of tool manufacture.The quality of brazing directly influences the strengthofcutting tool.By brazing experiment of YG8 cemented carbide and polycrystalline diamond compact in caacuum environment and analysing the changes of wettability and strength of three kinds of solder under different temperature and holding time to determine the best brazing parameters and application range of the three kinds of solder.At the same time,the effect of using stop-off agent on the solder flow resistance is compared and analyzed.The results show that the stop-off agent can effectively control the solder overflow to the non-brazing surface. |
