Wear resistant, sintered alloy

Abstract

Abstract PURPOSE: To provide a sintered alloy of high density, high hardness, and excellent wear resistance in sliding parts used at high surface press., by sintering under limited conditions metal powder comprising specific amounts of Cr, Cu, P, C, or Mo in addn., the balance being Fe and impurities. CONSTITUTION: Metal powder comprising 15W25% Cr, 1W5% Cu, 0.3W0.8% P, 2W4% C, or in addn. ≤3% Mo, the balance being Fe and ≤2% impurities, is sintered to a density not less than 7.3 g/cm 3 . Hereby, wear resistant Fe base sintered alloy of high hardness of 400W700 in Vickers hardness, having material strength resistant to high surface press. is produced. This alloy is advantageous for the production of automobiles of high performance and long life, being utilized in wearing parts, to which high surface press. is applied, e.g., cams rocker armpads, valve lifters, or valve tips of internal combustion engines.
