A process for making a multilayer bearing material is provided which comprises a backing layer, an intermediate layer of aluminum and an outer overlay layer. The backing layer and aluminum layer are roll bonded together to form a composite strip which is then fed into a molten bath of overlay material which provides for good adhesion to the aluminum and also for good bearing material properties. The aluminum surface of the composite is then cleaned to remove surface oxide and the composite is removed from the bath into a guide means and through a gate which controls the thickness of the overlay so that upon solidification of the molten overlay material a finished bearing material is produced. The fusion bonding of overlay material to the composite is performed in a single operation. |
