the main components of the tungsten carbide (WC) and cobalt (Co) for cemented carbide Milling-digging bits,which has the very good stiffness, strength, high melting point, excellent wear resistance and chemical stability, so its in oil drilling and geological drilling has been widely used in industries. Carbide ball is on the set in the bit teeth, to shock, rotating, crushed rock and shear to achieve the effect of mining. As most of the drilling depth is deeper, digging length is longer, some may reach thousands of meters, if the ball tooth due to wear and fracture or other reasons, many bit change will seriously affect the drilling efficiency of the whole.
As a result, this also for hardness and wear resistance of cemented carbide Milling-digging bits put forward higher requirements. And its mechanical properties and physical properties depend on composition and structure, the original properties of WC powder, especially physical performance directly determines the carbide ball tooth structure. WC powder and the quality of tungsten powder reduction process is inseparable, in order to get high quality WC powder, we need to combine tungsten powder reduction and optimize process parameters, makes the performance of hard alloy ball tooth have been improved greatly.
