In order to obtain high thermal stability high abrasion resistance, high impact resistance of polycrystalline diamond conducted extensive research

Under conditions of high temperature and pressure to obtain single-crystal diamond sintered superhard materials in petroleum, geological drilling has a wide range of applications.  cubic boron nitride , scholars at home and abroad in order to obtain high wear thermal stability, high resistance impact resistance polycrystalline diamond of extensive research. polycrystalline diamond performance and the choice of  synthetic diamond synthesis conditions are closely related to the type of adhesive for different synthesis conditions, its performance varies mainly we have  polycrystalline diamond a thermally stable polycrystalline diamond conduct research to identify the temperature of its thermal stability, and using diffraction, the impact of polycrystalline diamond abrasion and thermal stability factors preliminarily.
