  • Polycrystalline diamond (PCD) is sintered under high pressure and high temperature conditions with diamond as the skeleton material and binder as the bonding material. Due to its excellent hardness and good wear resistance, PCD is widely used in cutting tools, drawing die and other fields. In this paper, the binder types, the preparation methods and the factors affecting PCD performance were summarized. The binding mechanism, the advantages and the disadvantages of three types of PCD, namely metal binder, ceramic binder and cermet binder, were introduced respectively. The differences between the preparation methods were compared. Cermet PCD, which combined the good performance of metal PCD and ceramic PCD, had become an important research direction.
