Corrosion Behaviour of Aluminium and AA5754 Alloy in 1% Acetic Acid Solution in Presence of Laurel Oil

摘要

Electrochemical investigations show that aluminium and AA5754 alloy have certain corrosion activityin 1% acetic acid solution. Results indicate that aluminium has better corrosion resistance to the actionof 1% acetic acid than its AA5754 alloy. The addition of ethanol solution of laurel oil in acetic aciddecreases the values of corrosion current densities and increases the polarization resistance. Corrosioninhibition effect of laurel oil is confirmed by SEM examination.
