FIELD: technological processes.SUBSTANCE: invention relates to metallurgy. Method includes application on surface of model of foamed polystyrene alloy composition is prepared by mixing dry powder mix containing titanium and amorphous boron, titanium weight ratio to weight of amorphous boron content is from 0.42 to 9.00, with adhesive binder. Content of components, wt%: dry powder mixture of titanium and amorphous boron is 95÷10 %, adhesive binder is 5÷90 %.EFFECT: alloying composition materials enable SHS reaction during shaping of casting, which enables to obtain doped layer with high hardness, preset thickness and composition of castings from iron-carbon alloys.12 cl, 2 ex |
