Polycrystalline diamond compact with enhanced thermal stability

Thermal stability is an important performance parameter of polycrystalline diamond compact. This paper focuses on the research for test method of PDC thermal stability performance. With the improvement method, the thermal stability performance of PDC with five typical macroscopic interface structure such as planar structure, v-groove, u-groove, ring groove, ring claw-tooth are tested at normal temperature and after heating, With SEM, we study on its mechanism of thermal stability performance due to different macroscopic interfaces structure, analyze the reason why PDC thermal stability performance is different with the changing of PDC macroscopic interface structure. The research result shows that the temperature influenced the wear property and the anti-impact property of PDC obviously. And it has great influence on the anti-impact property. The thermal stability of the vessel-shaped interface structure is better than the flat interface structure.

Polycrystalline Diamond Compact

The electrical and physical properties of the electrically conductive super hard material on the basis of polycrystalline diamond and n-layered graphenes obtained at high pressures and temperatures were studied. It was established that the increase in graphene in a polycrystalline diamond compact leads to a sharp decrease in resistance. Wherein the hardness of the samples is slightly inferior to the hardness of diamond poly crystals obtained without the use of graphene.
