Abstract
The effect of voltage and concentration of electrolyte on the structure of porous anodic alumina (PAA), via electrochemical anodizing of aluminum alloy was studied. The weight change, roughness and corrosion rate were measured. Nano porous anodic alumina templates are fabricated following the one-step anodizing at room temperature, (5, 10,20 and 40) volt and (5%, 15% and 30%) concentration (H3PO4) . Formation of barrier oxide layer in 5% concentration at (5 and 10) volt and the porous oxide layer was formed at another conditions. When the anodizing voltage increases the roughness and the corrosion rate increases
