Studying properties of chrome cast irons modified with titanium carbide

Abstract

The paper presents the results of studying hardness and wear resistance of chrome cast irons. In the study there were considered samples of cast iron of the ChN2H, ChN4H2 grades and ChN2H after treatment with titanium carbide. Titanium carbide in the amount of 1 % by weight with dispersity of 500 microns was introduced during casting into ChN2H cast iron. As a result of this treatment, the cast iron hardness and wear resistance become comparable to those of Nihard grade cast iron. Studies have shown the promise of using refractory compounds as modifiers for cast irons.
