FIELD: process engineering.
SUBSTANCE: invention relates to thermomechanical processing of parts and can be used for surface hardening of friction working surfaces of rails and rolling stock wheels. Particularly, it relates to surface hardening of wearing surfaces of parts, primarily, rolling surfaces and railway mounted axle flanges. Strips with modified structure are produced that feature mechanical properties other than those of mother metal. Note here that said strips vary in width and depth over the wheel flange circle.
EFFECT: higher wear resistance, longer wheel life.
