IRON-BASED SINTERED ALLOY, VALVE SEAT RING, RAW MATERIAL POWDER FOR PRODUCING IRON-BASED SINTERED ALLOY AND METHOD OF PRODUCING IRON-BASED SINTERED ALLOY

摘要

PROBLEM TO BE SOLVED: To provide a hard dispersion type iron-based sintered alloy which has excellent wear resistance without copper infiltration.;SOLUTION: The iron based sintered alloy is obtained by dispersing hard particles of 3 to 20 wt.% to the whole into a matrix comprising 3 to 12% Ni, 3 to 12% Mo, 0.1 to 3% Nb, 0.5 to 5% Cr, 0.6 to 4% V, 0.5 to 2% C and Fe with inevitable impurities.;COPYRIGHT: (C)2005,JPO&NCIPI
