Description
Summary:The present study is aimed at investigating the electrochemical characteristics of aluminium due to the incorporation of nano metre and micro metre sized cerium oxide mixture. Treated aluminium exhibits higher corrosion resistance as evidenced by lower corrosion current density and corrosion rate and improved morphologies. Impedance spectra of aluminium subjected to long term exposure to 3.5% NaCl (w/v) show that the corrosion resistance of surface and internal matrix increases significantly and the corrosion is occurred in the (3 spaces of the aluminium. Smaller grain size and increased electronic conductivity improve the corrosion resistance of aluminium.
