In this study, we aim to enhance physical and chemical properties of 7075 aluminum via anodizing. For this purpose, convenient potential, current density, time, electrolyte type and its concentration were determined. The corrosion performances of non-anodized and anodized samples have been investigated in 3.5% NaCl by using EIS, polarization techniques. The surface morphology was determined with SEM. As a result, additive (0.5 M C2H6O2 + 0.08 M H3BO4 + 10(-3) Al+3) used in 0.4 M H2SO4 was improved the quality of aluminium oxide by blocking pores, increasing the thickness and decreasing the oxide formation potential. It was achieved corrosion resistance.
