Study on Discharge Parameters of Surface Strengthening with Powder Mixed Near Dry EDM for H13 Steel

Abstract:

Surface strengthening for H13 steel with powder mixed near dry EDM, research the effect of different discharge parameters on the microstructure and hardness of strengthened layer .The results show that the effect of pulse interval on microstructure and micro hardness is not obvious, the influence of the pulse width less than the peak current. As the increasing of peak current, strengthening layer surface quality get better, when the peak current reach to 14A , preferable microstructure of strengthening layer can be obtained.
