CASTS SURFACE ALLOYING METHOD FOR IRON-CARBON ALLOYS

摘要

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. The powder mixture has the composition: 60÷90 wt % titanium and 40÷10 wt % elemental carbon.;EFFECT: materials included into the alloying compound provide the SHS reaction in casting forming, which permit to obtain the alloyed layer of high hardness, of the specified thickness and composition on the iron-carbon alloy castings.;12 cl, 2 ex
