Chromic acid anodizing enhances the corrosion resistance of aluminum parts and produces a thin opaque film that is soft, ductile, non-conductive, and to a degree self-healing. A typical thickness is usually 0.00005-0.0001 inches. Chromic anodize may be applied as a pretreatment before painting to enhance adhesion and it is harder to dye than sulfuric acid anodize. The big advantage of the chromic acid anodizing process over other anodizing processes is that it does not lower the fatigue strength of the aluminum or damage the base material if it is entrapped in lap joints or blind holes. After chromic acid anodize, the solution may be sealed in either hot water or sodium dichromate solutions.
