FIELD: metallurgy.
SUBSTANCE: charging and grinding of a mixture of powders of high-melting compounds and cobalt are performed for manufacture of hard alloy with controlled distribution and quantity of carbon in its volume. At grinding, nanodisperse powder of tungsten with grain size of 30-100 nm in the quantity determined as per the below formula is added in addition to the charge: Pwh=3.88×K/6.12, where PWh - quantity of tungsten quantity; 93.88 -quantity of tungsten in WC; 6.12 - quantity of carbon in WC; K - total carbon potential. The obtained mixture of powders is pressed and sintered.
EFFECT: method ensures the possibility of obtaining alloys with the specified quantity of carbon within two-stage area and containing no excess carbon in the form of an individual phase.
