Metal-ceramic permeable SHS-materials based on alloy-steel scale and ilmenite for cleaning exhaust gases of diesel engines

Abstract

The possibilities of obtaining porous permeable cermet SHS-materials with catalytic properties are studied. The mixture consisted of powders of steel alloy scale, concentrate of ilmenite, oxides of aluminum or chromium, the basis of the material formed the backbone of metal ceramics (Al2O3) and reduced iron, as well as additives of metal oxides. The resulting material is intended for the catalytic purification of exhaust gases of diesel engines, in particular, from nitrous oxide, carbon monoxide and soot.
