FIELD: technological processes.SUBSTANCE: invention relates to metallurgy. Method includes application on surface of model of foamed polystyrene of alloy composition, which is prepared by mixing dry powder mix containing titanium and boron carbide, titanium weight ratio to weight of boron carbide is from 0.66-9.00, with adhesive binder. Content of components, wt%: dry powder mixture of ferro-titanium and boron carbide 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 |
