される。The bearing material obtained by the first invention is
Since Cu or Cu-Pb that contributes to seizure resistance is three-dimensionally present over the entire base material, even if the surface layer wears, Cu or Cu-Pb appears uniformly one after another and is stable for a long period of time. The seizure resistance can be maintained. Moreover, the reason why the abundance ratio of the Cu or Cu-Pb powder is 50% or more in terms of the cross-sectional area ratio is that the effect of the seizure resistance does not appear below this. The bearing material <br/> obtained by the second invention, exhibit more excellent galling resistance. That is,
Al-Sn-Cu atomized powder and Cu or Cu-P
b When mixed with atomized powder and sintered, Cu or Cu-
The Cu component of the Pb atomized powder and the Al component of the Al-Sn-Cu atomized powder react during sintering . to this
Thus, a hard intermetallic compound of Al and Cu are formed on the surface layer of the powder, an intermetallic compound of this will cause a temperature increase when the friction with the mating member, slightly decreasing the seizure resistance. Thus, in the second invention, only sentence subjected to Ni or Cu plating to the Al-Sn-Cu atomized powder surface, but the manufacturing process becomes slightly complicated, the occurrence of the hard intermetallic compound is prevented, Further improvement in seizure resistance is achieved.
