Polycrystalline diamond compact blanks (PCD for short) is a composite super hard material made of a mixed diamond powder and a cemented carbide matrix sintered under high temperature and pressure.The diamond crystals in the diamond layer of PCD are arranged in a disordered manner, isotropic, and have no cleavage surface. They have the high hardness, high wear resistance and high thermal conductivity of diamond; the cemented carbide layer as the substrate has high impact toughness and weldability.Therefore, PCD is particularly suitable for cutting tools of non-ferrous metals and non-metallic materials and supporting wear-resistant parts of various instruments and equipment.
