Abstract: A method of coating a ferrous base metal with aluminum including cleaning the surface of the ferrous article by means of an aqueous solution of orthophosphoric acid having a concentration of about 5 to 85 percent. Subsequently, drying the surface to evaporate the water from said solution. Applying molten aluminum to the ferrous surface to establish a uniformly bonded aluminum coating by means of a layer of ferrous-aluminum intermetallic compound. The molten aluminum application being effected without any additional application of fluxing material to the ferrous surface after the cleaning operation.
