Influence of chromic acid anodizing on the fatigue strength of overaged 7000 series aluminium alloys. Part I: Surface attack after anodizing

The influence of different variables in the chromic acid anodizing process on the surface attack and the thickness of the anodizing layer was investigated for aluminium alloy 7050-T7451 (formerly T73651) plate, 7075-T7351 plate, 7075-T6 forgings and 7075-T73 forgings. A preliminary investigation was carried out to enable the selection of a...
