Title:
SYNCHRONIZER RING MADE OF IRON-BASE SINTERED ALLOY, AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP2000034548
Kind Code:
A
Abstract:
To provide a synchronizer ring made of iron-base sintered alloy, excellent in strength, toughness, and wear resistance.
The alloy has a composition consisting of, by weight, 15-40% Cu, 0.5-15% Ni, 0.0005-0.85% C, and the balance Fe with inevitable impurities and also has a structure constituted by binding an Fe-base alloy phase composed essentially of Fe with a Cu-base alloy phase composed essentially of Cu. The Fe-base alloy phase is an Fe alloy phase containing Ni, Cu, C, and ≥50 wt.% Fe. The Cu-base alloy phase is a Cu alloy phase containing Ni, Fe, C, and ≥50 wt.% Cu. Further, respective concentrations of Ni and C contained in the Fe-base alloy phase are higher than those of Ni and C contained in the Cu-base alloy phase.
