DEVELOPMENT OF A CONTINUOUS, HARD-ANODIZED ALUMINUM SURFACE

Abstract

A method is described for minimizing the effects of the discontinuities inherent in hard-anodized coatings on aluminum by the introduction of a secondary anodic film. Photomicrographs show the location of the secondary coating beneath the original hard-anodized finish. Data are presented which indicate that the method described has no ill effect on the original abrasion resistance and that the continuity of the coating is significantly increased.
