ABSTRACT:
A controlled method of anodizing aluminum comprises formation of an aqueous solution of sulfuric and boric acids, immersion of a workpiece in the solution maintained at about room temperature and controlled application of voltage to achieve a current density not greater than about 10 Amperes per square foot. Aluminum oxide coatings in the weight range of from about 200 to 600 milligrams per square foot applied in this manner have properties as good as or superior to coatings applied in traditional hexavalent chromium anodizing solutions.
