Mechanism of the effect of Interface Structure on the Abrasion Performance of Polycrystalline Diamond Compact
Abrasion performance is an important performance parameter of polycrystalline diamond compact.This paper focuses on the research for test method of PDC abrasion performance.With the improvement method,the abrasion 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 abrasion performance due to different macroscopic interfaces structure,analyze the reason why PDC abrasion 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.In the same technological conditions,the interfacial structure of the PDC layer and WC-Co substrate has little influence on the abrasion performance,and the diamond and grains can sinter better,causing the excellent abrasion performance of PDC.
