Abstract
612,478. Electrolysis. MAcARTHUR, D., WESTWOOD, J. V., NAPIER, D. H., and UNITED ANODISING, Ltd. May 24, 1946, No. 15861. [Class 41] In a process for electro-polishing aluminium work wherein the work is treated as an anode in a bath containing orthophosphoric acid, an organic substance inhibiting dissolution of the metal surface by the acid, and water, the bath also contains sufficient sulphuric acid to obviate unsightly etching of the work in the absence of electric current during the time normally required to arrange the work in the bath. Preferably, the proportion by volume of sulphuric acid to orthophosphoric acid is between 1 to 6 and 2 to 1, and the total acid is between 45 and 65 per cent by volume of the whole bath. The organic inhibitor may be an alkylene glycol or its ether, as in the process described in Specification 558,925, but other organic inhibitors, for example glycerol, may be used. The liquid in the bath may be without sulphuric acid at the commencement of the process, but be subsequently made up mainly by the addition of sulphuric acid. The work after treatment has a thin iridescent oxide film which may be removed by the process described in Specification 489,169. Specification 556,797 also is referred to.
