Abstract
The present study is aimed at investigating the electrochemical charactoristics of aluminum due to incorporation of nano meter and micro meter sized cerium oxide mixture. Treated aluminium exhibits higher corrosion resistance as evidence by lower corrosion current density and corrosion rate and improved morphologies . Impedance spectra of aluminium subjected to long term exposure to 3.5% NaCi (w/v) show that the corrosion resistance of surface and internal matrix increases significantly and the corrosion is occured in the β space of the aluminium. Smaller grain size and increased electronic conductivity improve the corrosion resistance of aluminum.
