Sliding bearing

摘要

A multi-layer type sliding bearing of aluminum alloy and a method of producing the same are disclosed. The multi-layer type sliding bearing includes a mixture layer which has a thickness of not more than 0.5 microns and which is constituted by a mixture of the constituents of the overlay and one element selected from the group consisting of Ni, Co and Fe. The mixture layer is provided between the overlay and a bearing layer of aluminum alloy. In order to prevent fretting, a 0.1 to 5 micron thick plating layer may be provided on the surface of a backing layer of steel which is located on the rear-face side of the bearing. This plating layer consists of the constituents which are the same as those of the overlay.
