ABSTRACT:
In order to ensure in sliding surface bearings a uniform distribution of the load over the bearing metal layer, a phosphate layer serving as a sliding layer has been applied to the bearing metal layer.
In order to ensure a high resistantce to scuffing, the sliding layer is formed from an aqueous phosphating solution which contains 1.5 to 5.0 g/l Zn, 12 to 24 g/l Na, 11 to 22 g/l P.sub.2 O.sub.5, 17 to 33 g/l 16 to 30 g/l BF.sub.4, 20 to 39 g/l B(OH).sub.3 and 1.0 to 6.0 g/l NaF.
