FIELD: metallurgy.
SUBSTANCE: method includes applying to the surface of the polystyrene foam model of an alloying compound which is prepared by blending mix powder with glutinous binding agent, the content of which does not exceed 90% of the mix powder weight, notice that the mix powder has the following composition: 5÷80% titanium by weight and 70÷10% ferroboron by weight at the borron content of not less than 6%. The materials put into the alloying compound promotes the SHS reaction in casting forming.
EFFECT: obtaining on the iron-carbon alloy castings of an alloyed layer of high hardness, of the specified thicnkness and composition.
