SINTERED ALLOY SUPERIOR IN WEAR RESISTANCE

Provided is a novel sintered bearing superior to conventional ones in a wear resistance. The sintered bearing has a structure in which Ni-P alloy particles having an average diameter of 10 to 100 µm are dispersed in an amount of 1 to 20% by mass in a Fe-Cu-based sintered alloy base. The Ni-P alloy p...

More Information
Summary:Provided is a novel sintered bearing superior to conventional ones in a wear resistance. The sintered bearing has a structure in which Ni-P alloy particles having an average diameter of 10 to 100 µm are dispersed in an amount of 1 to 20% by mass in a Fe-Cu-based sintered alloy base. The Ni-P alloy particles are derived from a raw material powder comprising 1 to 12% by mass of P; and a remainder composed of Ni and inevitable impurities. The Fe-Cu-based sintered alloy base contains not larger than 50% by mass of Fe.
