In this study, the formation of porous Al2O3 on commercial 1050 aluminium alloy (AA1050) in 2[Formula: see text]M sulfuric acid (H2SO4) electrolyte was investigated. Anodization was performed at 12[Formula: see text]V and 15[Formula: see text]V specimens for a charge density of 757[Formula: see text]mC/cm2 and 3231[Formula: see text]mC/cm2. The resulting oxides were analyzed using scanning electron microscopy (SEM). According to analysis, a hexagonal oxide formation containing more than one nano pore was observed on the surface of the specimen. The structural properties of the porous oxide film were analyzed with electrochemical impedance spectroscopy (EIS) analysis and film-related features such as thickness of the porous and the barrier layer were obtained.
