In the manufacture of a bearing material containing an aluminium based alloy, one surface of a steel strip 1 is washed in a washing machine and roughened by a grinder 8. An aluminium based alloy powder 2'' is spread on the surface of the steel strip 1 and the aluminium based alloy and the steel strip are hot-rolled by heated rollers 5 in the ambient air to pressure-bond the aluminium based alloy to the strip to form a unitary structure. Prior to spreading the aluminum based alloy 2'', an aluminum powder 2' which enhances the bond to the steel strip 1 may first be spread on the surface of the steel strip 1. Also the strip 1 and the powder 2', 2'' may be heated by a heater 9a before the hot rolling. <IMAGE> |
