Abstract
Influence of oxalic acid (H2C2O4) addition to chromic acid (CrO3) has been examined for the anodising of Al 2024 alloy. Electrochemical tests have been revealed significant dependence on the oxalic acid concentration. The role of electrolyte temperature has also been studied. A beneficial effect has been observed concerning the increase of H2C2O4 addition and temperature. They have affected the oxide film growth, modifying the morphology and improving the corrosion performance of anodic films.
