FIELD: transport.
SUBSTANCE: plasma surface hardening is performed by plasma generator with work gas flow converter that has slit-like outlet. Flow converter face surface is made to fit processed part shape. In processing, slit-like outlet is located at α=30-60° to generatrix of converter face surface. Processing is performed with overlap of processing strip, overlap length making l≥h·-tgα, where h is the processing strip width.
EFFECT: notably reduced extension strain, higher efficiency of surface hardening.
