FIELD: metallurgy.
SUBSTANCE: first, preliminary local surface boration is performed using laser heating from a coating material containing boron or its compounds. Then, thermodiffusion boron saturation process is performed at heating to the temperature T=850-950°C with exposure during 3-4 hours.
EFFECT: reduction of brittleness of borated layers; reduction of duration and temperature of a thermodiffusion saturation process of surface of parts at maintaining high hardness.
