The exfoliation corrosion behavior of 2524 aluminum alloy was studied by Transmission Electron Microscope (TEM), hydrogen evolution and Electrochemical impedance spectroscopy (EIS) . The results showed that 2524 aluminum alloy was very susceptible to exfoliation corrosion and the exfoliation corrosion appeared after 24 h. EIS could better explain the exfoliation corrosion than hydrogen evolution. Exfoliation corrosion kinetics included accelerated formation of pitting, quick development of pitting, retarded formation of exfoliation and steady development of exfoliation.
