PDC for oil drill bits series are produced by using the higher degree of diamond power and tungsten carbide substrate through adopting advancing American technology
Micro-structure with complete C-C bond combination is characterized between the grains of the diamond in polycrystalline diamond layer, which allows the high strength, hardness and durability of diamond layer
Adopts many types of claw structure of the interface between diamond layer and tungsten carbide substrate, 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 drill bits, PDC displays satisfying thermal stability, higher impact resistance and excellent performance
