Sintered material of fe-tic system for sliding member in internal-combustion engine

Abstract

Abstract PURPOSE:To improve both wear resistance of a material itself and its opponent offensiveness, by dispersedly providing a hard phase consisting of titanium carbide and chrome carbide in the matrix mainly consisting of martensite with the composition containing Cr, C, P, B, Ti with the rest of Fe or the like. CONSTITUTION:The composition of a material is arranged such that a hard phase consisting of titanium carbide and chrome carbide is finely and uniformly dispersed in the matrix of martensite containing by weight 1-15% Cr, 5-20% C, 0.1-2% one or two of P and B and 20-55% Ti, further if necessary 0.2-5% one or two of Mo, Nb, W, V, Zr, and 0.5-5% either one or two or both of Ni, Co, Cu, Mn with the rest Fe. By such a way, the sintered material, having excellent wear resistance and low opponent offensiveness, displays excellent performance for a long period when it is used for a sliding part.
