Abstract
The inhibition effect of cerium salts on iron/aluminum galvanic coupling was investigated by electrochemical microcell and Scanning Vibrating Electrochemical Technique (SVET). The importance of the electrode geometry on the SVET responses was evidenced. The effect of concentration and the influence of the anionic part of cerium salts on the inhibitive efficiencies and protective mechanisms were studied. Cerium salts inhibit the corrosion of iron/aluminum galvanic coupling by reducing the cathodic activity. Microcell analysis confirmed the passivation of aluminum. (SEMÂ +Â EDS) analyses allowed to understand how the cerium salts act to improve the corrosion behavior.
