The results of the linear sweep voltammetry of examined alloys and calculated parameters of polarization dependencies are listed in Fig. and Table , respectively. The value of the corrosion potential (Ecorr) was significantly affected by the amount of Li in the alloy and the concentration of permanganate ions in the corrosion media. Generally, the value of Ecorr was higher with an increase in these two parameters (Table ). The value of icorr extracted as the intersection of the corrosion potential with the extension of the cathodic Tafel region increased in a row AZ31-4Li → AZ31-8Li → AZ31-12Li, with icorr of 6.31•× 10 -5 , 8.32 × 10 -5 , and 1.26 × 10 -4 A/cm 2 , respectively. respectively. Upon the addition of different amounts of the inhibitor, these values were gradually higher, reaching the maximum at 150 mM of the inhibitor in the solution. The same trend followed the inhibitor efficiency and inhibition power (Fig. ). The only exception was observed for AZ31-12Li in the solution containing the smallest examined amount (5 mM KMnO4) of the added inhibitor, where IE and Pinh were slightly lower than in the reference chloride solution.
