Title:
SINTERED ALLOY HAVING EXCELLENT ABRASION RESISTANCE
Document Type and Number:
WIPO Patent Application WO/2013/129226
Kind Code:
A1
Abstract:
Provided is a novel sintered bearing having abrasion resistance superior to that of conventional products. The present invention is provided with a structure in which 1-20 mass % of Ni-P alloy particles having an average particle diameter of 10-100 μm are dispersed in a Cu-based sintered alloy base metal, Fe-Cu-based sintered alloy base metal or Cu-Ni-based sintered alloy base metal; the Ni-P alloy particles are derived from a raw material powder comprising 1-12 mass % of P, with the remainder being Ni and unavoidable impurities. The Cu-based sintered alloy base metal contains 40 mass % or more of Cu. The Fe-Cu-based sintered alloy base metal contains 50 mass % or less of Fe. The Cu-Ni-based sintered alloy base metal contains 20-40 mass % of Ni and 0.1-1.0 mass % of P or 10-25 mass % of Ni, 10-25 mass % of Zn and 0.1-1.0 mass % of P.
