FIELD: machine building.
SUBSTANCE: invention relates to thermal treatment of items from graphitised cast iron and can be used in power engineering, machine building, agricultural and other industries. For increasing wear resistance of articles from graphitized cast iron with ferrite matrix, article is heated by HF currents and subsequent quenching, wherein starting material used is iron with number of graphite inclusions of over 200 1/mm2, and induction heating rate is 400-500 deg/s.
EFFECT: increasing wear resistance of articles from graphitized cast iron with ferrite matrix.
