Abstract
In present study, the anodizing of aluminium was carried out in sulphuric acid/tartaric acid electrolyte system to increase pitting corrosion resistance. The corrosion resistance of the oxide coating of aluminium was determined by potentiodynamic polarization test. The surface morphology was investigated using scanning electron microscope before and after the corrosion test. It was found that anodic oxide coating obtained in sulphuric acid/tartaric acid showed higher pitting corrosion resistance.
