  • Method of manufacturing bearing material
    Patent number: 4071643
    Abstract: This invention is the production of a plain bearing having an aluminum interlayer and a metal overlay on the interlayer. The overlayer is for example cast on the interlayer so that it can constitute substantially the final bearing surface without machining after casting or roll-bonding. In order to enable the overlay to be cast on, the interlayer is abraded while below the surface of a tinning or other coating material in a material so that oxides can be removed from the aluminium surface and the coating applied to it without its becoming re-oxidised, and then the overlay can be applied to the coating.
