FIELD: machine building.
SUBSTANCE: method includes application on parts surface of facing charge, and its heating by HF currents. Prior to the facing charge application the dead-end holes are filled with charge containing 25-35% of boron carbide, 20-15% of flux and 50-60% of high alloyed chromous cast iron. Depth of holes filling is 1/3-1/2 of thickness of facing wearproof layer.
EFFECT: increased service life of parts due to creation of unfavourable structures during induction build-up.
