Research Status of the Main Performance of Polycrystalline Diamond Complex

During weighting three targets of PDC quality wear resistance, heat resistance, shock resisting toughness, based on the results of omni-directional test and research of PDC performances by domestic and foreign scholars, the performances of polycrystalline diamond complex and some primary influence factors on its performances are summarized, emphatically to the PDC surface graphitization, the oxidized phenomenon, choice of adhesive, improvement of contact surface shape, the granularity scope, the package program, sintering process and so on. The complex machine capabilities of some typical polycrystalline diamonds are reorganized to provide some references for the synthesis of diamond compound piece and its application in industry.
