Following our approach in the previous studies , in this section we aim to propose an inhibition mechanism provided by aqueous permanganate towards AZ31-xLi alloys in 0.05 M NaCl solution. For this, the chemical composition and surface morphology of the alloys were analyzed after corrosion in 0.05 M NaCl containing 150 mM of the permanganate inhibitor by SEM/EDX, Raman, and XPS spectroscopy. The same measurements in the reference NaCl solution without inhibitors are reported in our previous fully open-access publication and referenced here without duplication.
