Known are Cu—Pb based Kelmet alloys, Cu—Sn—Pb based lead bronze, and aluminum based alloys. Of these, aluminum alloys, in particular, have excellent wear resistance, corrosion resistance, and high load capacity, and are therefore used in most high-performance gasoline engines and small diesel engines in recent years.

As shown in FIG. 3, what is referred to as ZS is such that by providing a plating layer such as Cu between the metal layer formed on the back metal and the overlay, the lubricating component such as Sn in the metal layer is prevented. It is known that diffusion to the overlay side is prevented and the performance is lowered, and that galling resistance and seizure resistance after overlay wear are greatly improved.

止され、さらなる耐焼き付き性の向上が達成される。In the bearing material obtained according to the first aspect of the present invention, Cu or Cu-Pb, which contributes to seizure resistance, is three-dimensionally present throughout the entire base material. This Cu or Cu-Pb appears uniformly, and stable seizure resistance can be maintained for a long period of time. Also, this Cu or C
The reason why the abundance ratio of the u-Pb powder is 50% or more in terms of cross-sectional area ratio is that the effect of seizure resistance does not appear below this. Further, in the second invention, further excellent seizure resistance is exhibited. That is, when the Al-Sn-Cu atomized powder and the Cu or Cu-Pb atomized powder are mixed and sintered, the Cu component of Cu or the Cu-Pb atomized powder and the Al component of the Al-Sn-Cu atomized powder are burned. It reacts at the time of binding to form a hard intermetallic compound of Al and Cu on the surface layer of the powder, which causes a temperature rise at the time of friction with the mating material and slightly lowers the seizure resistance. Therefore, in the second invention, the production process is slightly complicated as much as Ni or Cu is plated on the surface of the Al—Sn—Cu atomized powder, but the generation of this hard intermetallic compound is prevented in advance. Improved seizure resistance is achieved.

The seizure resistance is improved by about 20% or more as compared with ZS.
