Abstract

The invention relates to thermal and chemical-thermal processing of parts for producing anti-friction coatings. A method for surface hardening crankshafts from iron-carbon alloys includes induction heating of the shaft journals and their hardening in 65 % aqueous solution of the sulfur-containing silicates and tempering. The technical result: increased wear resistance, tear- proofness, reducing the coefficient of friction and service life of the part.
