Abstract

The refractive indices and thicknesses of anodically formed oxides on both pure and 3003 alloy aluminum were determined using a transmission spectrophotometric technique. Dispersion curves were obtained for the films formed on both aluminums, and thicknesses were given as a function of voltage for Barrier-films and as a function of time for porous films. Characteristics of formation were reported for both types of films on pure and 3003 alloy aluminum. These formation characteristics are interpreted in terms of the solvent action of the anodizing electrolyte on the oxide. the refractive indices of porous films were found to change with time due to the presence of water in the films. A modification of the thickness calculation method is developed for these porous films. Incorporation of water and sulfate anion in the films were detected using infrared spectroscopy. The structures of the films were studied under the microscope, and related to certain aspects of their behavior.
