This study investigated the corrosion inhibition of the AZ31 magnesium alloy in NaCl solutions containing different concentrations of sodium molybdate inhibitor. Various experimental methods were used to examine the mechanism of molybdate corrosion inhibition. The results showed that Na2MoO4 inhibitor provided reliable inhibition at high concentrations (150 mM). Surface examination confirmed the formation of a protective surface layer of mixed Mo (VI, V, IV) species.
In this work, corrosion inhibition of the AZ31 magnesium alloy was investigated in NaCl solutions containing different amounts of sodium molybdate inhibitor. Electrochemical, hydrogen evolution, microscopic, and spectroscopic experiments were utilized to examine the mechanism of corrosion inhibition by molybdates. The results showed that Na2MoO4 inhibitor provides reliable inhibition at high concentrations (150 mM). Surface examination by Raman and XPS spectroscopy confirmed the formation of a protective surface layer of mixed Mo (VI, V, IV) species. Based on these results, the mechanism of corrosion inhibition of the AZ31 alloy by aqueous molybdates was proposed.
