Abstract

The possibility to increase the wear resistance and bending strength of Fe–Cr–C alloys with a high content of chromium carbide produced by powder metallurgy is studied. The regularities of structure and mechanical properties as a function of alloy composition and production conditions are determined. The conditions of sintering and composition of the alloys with a high content of chromium carbide ensuring high abrasive wear resistance, which is 1.5 times greater than that of alloy VK8, are found. The structure of the alloy is a composite of fine chromium carbides obtained by dosing of the liquid phase vanishing during sintering.
