Abstract: The corrosion behavior of aluminum alloy AA6061 in acetic acid (C2H402) and sulfuric acid (H2S04) have been carried out using weight loss measurement in temperature range of 283-333 K. Sodium benzoate has been used as a corrosion inhibitor to the corrosion process. The inhibition action depends on the chemical structure, concentration of inhibitors, concentration of corrosion medium and the temperature. Results for weight loss data indicated that the corrosion rate increased with increasing of temperature and the inhibitor efficiency decreased with the increasing of temperature. Scanning electron microscope (SEM) has shown that the AA6061 suffer from pitting corrosion. The presence of thin layer on alloy surface was confirmed by EDXS.
