In this study we examined the effect of topography and corrosion resistance of aluminum alloy 6061 which has been anodized on a mixture of phosphoric acid and oxalic acid by using titanium cathode. Surface topography was tested with the N8 NEOS Bruker, corrosion testing performed by Tafel method using a potentiostat Autolab (PGSTAT302N), while testing the immersed test to determine the condition of the surface corroded done using 3.5% NaCl fluids with immersion time of 500 hours. The results obtained indicate that the change in the surface is affected by the potential applied during anodization process. Increasing the potential shown to improve the contour of the growing prevalence of pore sizes formed after the anodizing process. The corrosion resistance is also increased with increasing potential.
