金刚石与钢体的盐浴焊

用氯基盐浴作为加热方法，实现了金刚石表面金属钛的渗覆以及金刚石与２０Ｎｉ４Ｍｏ钢的焊接。试验中采用了Ｎｉ基合金作为中间过渡层金属。试验结果表明：盐浴加热既可有效地避免金刚石在高温下的石墨化，又不影响金刚石的性能；利用金属Ｔｉ和Ｎｉ形成低溶点共晶，来实现金刚石与钢体的接触熔化焊，大大降低了加热温度，为金刚石工具的焊接技术开辟了一条有效途径。金刚石与钢盐浴焊具有加工成本低、操作简便、连接强度高的优点。

The Chloridebase Salt Bath Welding of the Diamond and the Steel,

This paper introduces that using the chloridebase salt bath as a heating method can titanize the surface of the diamond and weld the 20N 14Mo steel with the diamond together. The colomony was used as the interim layer metal between the diamond and the steel in the test. It was found that the diamond neither become graphite nor be weakened on its properties in the salt bath. In the process of realizing the contact welding of the diamond and the steel, Ti and Ni interact to form the lower fusion coexist crystal so as to largely lower the welding temperature. This opened up a valid way to the welding technology of the diamonjd tools. The salt bath welding is lower cost, easer to operate and it can significantly increase the strength of the joint.
