Mechanism of the Effect of Interface Structure on the Anti-Impact Property of Polycrystalline Diamond Compact

Abstract:

Anti-impact property 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 typicals 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 show that the temperature influenced obviously the wear property and the anti-impact property of PDC, and it has great influence on the anti-impact property. The anti-impact property of the vessel-shaped interface structure is better than the flat interface structure.
