The aerospace industry progressively develops alternatives for chromic acid anodizing, since Cr6+ is known to be toxic and carcinogenic. In this work, potentiodynamic anodizing of aluminum alloys AA1050 and AA2024-T3 clad was performed in phosphoric sulfuric acid (PSA) and sulfuric acid (SAA). I has been shown that anodic film morphologies can be ‘customized’ by choosing specific anodizing process parameters. Desired pore and cell diameters can be obtained throughout the film thickness by choosing the right voltage profile. However, the effect of the high rate of oxide dissolution in phosphoric acid has to be taken into account, because this leads to pore widening after prolonged anodizing. By constructing the right anodic film morphology, it seems possible to influence the strength and corrosion resistance of adhesively bonded aluminum joints.
