<p>Disclosed is a sliding bearing equipped with a reverse gold layer, an Al center layer, and an Al bearing alloy layer. The aforementioned Al bearing alloy layer is at least one type of intermetallic compound comprising Al and at least two other elements, and includes at least 8/μm2 of an intermetallic compound with a particle size of less than 0.5μm. The abundance ratio of the aforementioned elements (X1, X2, â â â ,Xn (n is a natural number)) that form the aforementioned intermetallic compound have the following relationship: X1 â § X2 â § â â â â § Xn. The abundance ratio (X1/X2) of the aforementioned element (X1) and the aforementioned element (X2) is in the range of 1 to 10. The aforementioned Al bearing alloy layer has a Vickers hardness in the range of 50 to 80.</p> |
