Abstract

The method for surface hardening of crankshafts from iron-carbon alloys includes induction heating, hardening and tempering. In this case, after induction heating of the crankshaft journals the hardening and tempering are carried out in a 65% water solution of sulfur-containing silicates with subsequent cooling to ambient temperature.
