%X Technological process of rare earth sealing anodized LY12 (2024) alloy is introduced. Corrosion behavior of the film was studied by polarization curves and electrochemical impedance spectroscopy (EIS). The results showed that the coating remained passivity at the potential range from the open circuit potential (-780 mV) to -250 mV in NaCl solution. When the potential exceeded -200 mV, corrosion reaction happened on the coating, the results of EIS analysis was consistent with the results of polarization curves.
