Abstract
The invention relates to the depositing of aluminum alloys useful as material for the manufacture of sleeve bearings. Aluminum and lead in the proper ratio are melted in a furnace, transferred to a holding furnace wherein the temperature of the melt is maintained within the molten range, and the melt is directed to an atomizing or nebulizing chamber. According to the invention, the molten material flowing into the atomization chamber is subjected to an atomizing gas flow having a specified angle of incidence to atomize the molten flow of alloy into small particles which are directly deposited on a continuous pure aluminum strip which moves under the atomization chamber at a preset rate, the aluminum strip with the alloy layer is submitted to a rolling operation and thereafter the strip is rolled together with a steel strip, to provide a cladding of the alloy-aluminum onto the steel of the backing and supporting strip.
