 | PDC is short of polycrystalline diamond compact. It is a new type of functional material. It is made by sintering diamond powder and cemented carbide substrate under ultra-high pressure and high temperature conditions. It not only has the high hardness, high wear resistance and thermal conductivity of diamond, but also the strength and resistance of cemented carbide. Impact toughness is an ideal material for manufacturing cutting tools, drilling bits and other wear-resistant tools. The diamond composite sheet has both the extremely high wear resistance of polycrystalline diamond and the high impact resistance of cemented carbide, and the diamond layer can always maintain a sharp cutting edge, so it is used in soft to medium hard formations in petroleum and geological drilling. very good. The diamond content in the composite sheet is as high as 99%, so the diamond layer has extremely high hardness and excellent wear resistance. Its Knoop hardness is (6.5～7)×104 MPa, or even higher. Its thickness is very thin, generally controlled at about 0.5 to 1 mm. Vertically inlaid and welded on the drill bit, its cutting edge is sharp and always keeps self-sharpening, also called micro-cutting tool bit.
