| 20100129011 | PLAIN BEARING - The copper alloy (lining) prevails in an overwhelmingly large amount in a plain-bearing layer structure. Cu of the plain bearing copper-alloy diffuses into the Sn-based overlay diffuses into the Sn-based overlay and detrimentally impairs the performance of the overlay. The present invention takes a measure against this problem. An Sn-based overlay having a thickness of 3 to 19 μm is deposited by electro-plating without an intermediate layer for diffusion prevention on a plain-bearing layer, which contains Sn and Ni in a total amount of more than 4 mass % to 20 mass % (the minimum amount of Sn is 4 mass %) and has a hardness of Hv 150 or less. | 05-27-2010 |
| 20100111753 | Pb-FREE COPPER-BASED SINTERED SLIDING MATERIAL - [Task] The adhesion resistance of Cu—Bi based or Cu—Sn—Bi based alloy is lower than that of Cu—Sn—Pb based alloy, and also since conformability of the former alloy is low. Therefore, when Bi of the former alloy adheres onto an opposite shaft, seizure of the former alloy is likely to occur as compared with the case of the latter Cu—Sn—Pb based alloy. In is alloyed in the Bi phase of the Cu—Sn—Bi—In based copper alloy. The In-alloyed Bi phase has a considerably low melting point and therefore the sliding properties deteriorate. | 05-06-2010 |
