Özet

In this study, the formation of porous Al2O3 on commercial 1050 aluminium alloy (AA1050) in 2 M sulfuric acid (H2SO4) electrolyte was investigated. Anodization was performed at 12 V and 15 V specimens for a charge density of 757 mC/cm(2) and 3231 mC/cm(2). 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.
