Abstract

The article describes the results of an investigation of the feasibility of using an electromechanical surface treatment as a means of hardening automobile engine crankshafts reconditioned by high-frequency induction metallizing. Metallographic examination of the metal structure, determination of residual stresses in the connecting rod journals and fatigue tests on actual parts established that electromechanical hardening ensures a high endurance of crankshafts reconditioned by high-frequency metallization.
