PDC-Polycrystalline diamond compact is composed of polycrystalline diamond layer and tungsten carbide substrate. The polycrystalline diamond layer possesses extremely high hardness and abrasion resistance whereas the tungsten carbide substrate would greatly improve the malleability and weld ability of the whole composite. The polycrystalline diamond compact is used in oil well drilling petroleum, geology exploring, coalfield mining and mechanical industry.
