Study of the Effect of input Parameters on Surface Characteristics of 38MnVS5 Micro Alloyed Steel Crankshaft in the Induction Hardening Process

In present research, the influence of input parameters in induction hardening process (power, current, induction time and, the gap between inductor's coil and crankshaft) on metallurgical structure changes, depth of hardened layer and magnitude of surface hardness has been investigated. The results suggest a direct relationship between power and current induction time, with depth of hardened layer and surface hardness. The results show that with increase of power and current induction time, surface hardness is increased. Also, with increase of gap between coil and crankshaft, it was observed that the width of hardened zone declines.
