Application of Diamond Tool Materials in Geological Drills

What applications of diamond tool materials in geological drills have? Electric spark sintering process has its outstanding characteristics for synthetic diamond tool materials sintering.

The strength loss and brittle tendency of synthetic diamond become larger and larger with the temperature rising and heat preservation time lengthening. In order to retain more strength properties of synthetic diamond, we should try to reduce the sintering temperature and shorten the time of heat preservation. General cold press sintering and hot-pressing sintering methods can be used for manufacturing diamond saw blade, and different binding materials need different sintering temperature.

It still needs a few minutes or tens of minutes to complete sintering mostly under the high temperature of  above 700 ℃. Diamond saw blades are mainly used for the cutting of stone materials, glass, and gemstone. The electric spark sintering can help make the wear resistance increased by 15% compared with general sintering process.

On the geological drills, foreign experts have used electric spark sintering to strengthen supporting part of oil drills. At the same time, the cutting edges by using electric spark sintering to make oil drills is also in progress.

As a result, the electric spark sintering process has become possible in the geological exploration industry, and the present work is to enlarge the range of electric spark sintering process. Not for a long time, the electric spark sintering will become an important production process in the production of synthetic diamond drills, and these synthetic diamond drills will not only have good performance, but also can get satisfactory effect on the economic benefits.
