This paper focuses on the research for the performances of 5 typical macroscopic interfaces at normal temperature and after heating, such as, planar structure, v-groove, u-groove, and ring groove and ring claw-tooth. With SEM, we study on different impact resistance for PDC due to these 5 typical macroscopic interfaces, analyze the reason why PDC performance varies with macro interface changes of WC-CO alloy, and find it greatly eliminates PDC internal defect and improves impact resistance if the macro interface of WC-CO alloy is multi-plane shape (e.g. ring claw-tooth).
