Resumo: In this research the effect of samarium on the corrosion behavior of different steels in NaCl + Sm (III) solutions is studied by electrochemical methods. The results allow the evaluation of the efficiency of samarium as a corrosion inhibitor by the kinetic parameters of the oxygen reduction reaction and the electrochemical behavior of the steels. The behavior observed depends on the nature of the steel, and the inhibition phenomenon is associated with a surface modification due to a hydroxy-samarium compound layer formed at the steel surface, as confirmed by EDS studies.
