Abstract

PURPOSE: To provide a sintered iron alloy material with superior wear resistance and machinability by adding a specified amount each of Cr, Ni and Mo to Fe and uniformly dispersing fine Fe-C-Cr composite carbide in the martensite matrix.
CONSTITUTION: Metal powder for a sintered alloy is prepared using a high C alloy steel contg. 1.0W3.0% C, 6.0W13.0% Cr, 0.5W2.0% Ni and 0.5W2.0% Mo. This powder is mixed with 1% zinc stearate as a lubricant, compacted in dies, and sintered by heating in a decomposed ammonia atmosphere. Fine Fe-C-Cr composite carbide is uniformly dispersed in the martensite matrix with superior wear resistance, resulting in enhanced wear resistance and machinability. Sealing such as Cu infiltration is very effective in case of parts requiring airtightness.
