Abstract An inclined impact failure method was proposed. It could impact and damage the polycrystalline diamond side in polycrystalline diamond compact. The impact failure fracture face of polycrystalline diamond in polycrystalline diamond compact was investigated by means of digital tool microscope and scanning electronic microscope and the impact failure mechanism of the polycrystalline diamond was discussed.
