Polycrystalline diamond compact (PDC) is a superhard composite material made by sintering diamond micro powder as raw material and WC hard alloy as matrix through specific synthesis process under high temperature and high pressure conditions. Composite sheets have the advantages of high diamond hardness, good wear resistance, and strong impact resistance of hard alloys. They have now expanded from the use of deep well drilling to various fields such as mineral exploration and mechanical processing. Wear resistance, as an important characteristic of PDC use, is generally characterized by the wear ratio parameter. PDC manufacturers are
