The paper presents results of research on steel castings GX120Mn13 (L120G13 by PN-89/H-83160), zone-reinforced by elektrocorundum particles (Al2O3), with a grain size from 2 to 3.5 mm. Studies revealed continuity at interface between composite components and formation of a diffusion zone in the surface layer of electrocorundum grains. In the area of this zone, simple manganese segregation and reverse iron and chromium segregation were found. The transfer of these elements from cast steel to electrocorundum grains resulted superficial depletion in aluminum and oxygen in this area. No porosity was observed at the interface between two components of the composite. We found it very beneficial from an exploitation point of view, as confirmed by the study of resistance to abrasive wear.
