Using the higher degree of diamond powder and tungsten carbide substrate through adopting the advanced international technology produces PDC for oil well drilling bits series. Microstructure with complete C-C bond combination is characterized among the grains of the diamond in polycrystalline diamond layer by using the new type and high effective accelerant, which allows the high strength, hardness and wearing property of diamond layer.
We adopt many types of claw structure of the interface between diamond layer and tungsten carbide substrate, and use the special technological late conditions in order to effectively reduce residual stress of PDC while make the interface combination firmer and more symmetrical. So applied to oil well drilling bits, PDC displays satisfying thermal stability, high impact resistance and excellent performance.
