FIELD: metallurgy.
SUBSTANCE: proposed method involves pre-cleaning of the steel product surface to be coated; application onto cleaned surface of the product of a flux layer by means of a gas-powder surfacing method with warm-up of the processed part of the product of up to the temperature of 450-600°C at use of propane-butane gas mixture; submersion of the product into molten wearproof steel at the melt temperature of 1560-1650°C; exposure in the melt during the period of time, which is required to obtain a coating of the required thickness; removal of the product with the coating out of the melt with further slow cooldown of the product with the applied coating in the air or together with a tight furnace with initial temperature of 500-600°C.
EFFECT: invention allows obtaining wearproof coatings with thickness of several millimetres applying a simple and economic method.
