Abstract
614,909. Electrolytic polishing. STEVENS, A. H. (Battelle Memorial Institute). Dec. 18, 1944, No. 25363. [Class 41] Stainless steel is polished by anodic treatment in a bath containing 0.1-85 per cent of phosphoric acid, 0.1-65 per cent of CrO3 and 13- 66 per cent of water, the proportions further lying within the area of the figure ABCD on the tri-axial diagram; preferred proportions are those within the figure ABFE. The proportions of phosphoric acid are stated in terms of orthophosphoric acid and may be replaced by stoichiometrically equivalent proportions of meta- or pyrophosphoric acids. Ingredients introduced into the bath by anodic solution of the metal are not harmful. The current density may be 100-1000 amps. per sq. ft., and the bath temperature 80-175‹ F.
