FIELD: metallurgy.
SUBSTANCE: invention concerns ferrous metallurgy field and mechanical engineering. Particularly it concerns cyanidation methods of steel or titanic products. Method includes application on working surface of product of diffusion layers containing carbon and nitrogen. Diffusion layers application is implemented by means of electroerosion alloying by graphite electrode, cooled by gaseous nitrogen.
EFFECT: increasing of microhardness and wear resistance of received layers.
