SINTERED ALLOY SUPERIOR IN WEAR RESISTANCE |
| 摘要 |
A 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 Cu-based sintered alloy base, a Fe—Cu-based sintered alloy base or a Cu—Ni-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 Cu-based sintered alloy base contains no less than 40% by mass of Cu. The Fe—Cu-based sintered alloy base contains no more than 50% by mass of Fe. The Cu—Ni-based sintered alloy base contains 20 to 40% by mass of Ni and 0.1 to 1.0% by mass of P; or contains 10 to 25% by mass of Ni, 10 to 25% by mass of Zn and 0.1 to 1.0% by mass of P. |

1. A Cu-based sintered alloy having 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 Cu-based sintered alloy base that contains no less than 40% by mass of Cu and selectively contains 0.2 to 8% by mass of a solid lubricant, wherein said 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. |
