ABSTRACT:
In the described process of manufacturing a sliding surface bearing comprising a backing shell of steel, a bearing metal layer on the backing shell, and a copper-containing sliding surface layer, which has been electrodeposited over said bearing metal layer, the backing shell is provided throughout its rear surface, which constitutes the rear surface of the bearing, with a tin-containing corrosion-resisting layer after the sliding surface layer has been deposited. To prevent a separation of the corrosion-resisting layer, it is proposed that the rear surface of the bearing is covered with an electrodeposited nickel layer before the sliding surface layer is deposited on the bearing metal layer or on an intermediate layer of nickel provided on the bearing metal layer.
