ABSTRACT:
A multilayer aluminum-based alloy plain bearing having superior compatibility and superior fatigue resistance, comprising a steel back metal, an aluminum alloy intermediate bonding layer bonded to the steel back metal, and an Al--Sn--Si family bearing alloy layer bonded to the intermediate bonding layer, the aluminum bearing alloy layer consisting, by weight, of 7 to 15% Sn, 0.5 to 3% Si, and the balance Al and incidental impurities, the hardness of the aluminum bearing alloy layer being less than 50 Vickers hardness, the aluminum alloy intermediate bonding layer consisting, by weight, of at least one kind selected from the group consisting of 0 to 1.7% Mn, 0 to 1.2% Cu and 0 to 1.8% Mg, and the balance Al and incidental impurities, Vickers hardness of the aluminum alloy intermediate bonding layer being in a range of not less than 60% of the Vickers hardness of the aluminum bearing alloy layer but not more than 120% of the Vickers hardness of the aluminum bearing alloy layer.
