Abstract

TiC-Fe-Cr alloys prepared from titanium-carbide and steel basis metal by powder metallurgy were studied with concerning their corrosion and abrasion resistance in water. Such alloys is used for preparing of pieces exposed to corrosion. Our experiments have indicated that the abrasion is not independent for corrosion resistance. By weak corrosion resistance abrasion decreases too because that the corroded metal do not bound together the hard titanium-carbide grains. Good abrasion is only by good corrosion resistance attainable. The corrosive abrasion is dependent on the hardness only in the case of suitable corrosion resistance of the solid alloys.
