Investigation into the electrical parameters to the diffusion of Tungsten into the SKD61 Steel by electrical discharge machining using the tungsten carbide powder mixing in the oil dielectric ☆

In the study, the authors studied the effect of the electrical current (Ip); the time on discharge (Ton) affect the diffusion of tungsten mixing in the oil dielectric to the surface of SKD61 steel at different concentrations. The research has shown that the electrical current; the time on discharge can impact greatly affect the diffusion of tungsten and the process carbide of the surface. In the mode parameters of the low electrical discharge (Ip; Ton), the diffusion of tungsten into the surface and the process carbide of the surface better than the mode parameters of the high electrical discharge. ab
