The results of the SEM analysis of the surface of AZ31-xLi alloys after exposure to the 0.05 M NaCl solution without the inhibitor for 1 and 24 h are shown in Fig. . After 1 h of exposure, all samples undergo general corrosion with some local corrosion attack in the periphery of IMPs. The regions around severe local corrosion spots were covered with a rather thick layer of corrosion products. The surface of the alloys' matrix was also covered by a layer of corrosion products and corrosion damage increased with an increase in Li content in the alloy. In the case of the AZ31-8Li alloy, the presence of filiform corrosion was observed, which most probably occurred on the boundaries of α and β phases . In turn, after 24 h of exposure of the samples to the corrosive environment, almost the entire surface was covered with an uneven, thick layer of corrosion products, the structure of which differs somewhat depending on the Li content in the alloy. The difference in the corrosion morphologies between studied alloys is explained by the different phase composition of the alloys (Fig. ) and pH values in the near-surface layer of the electrolyte and, accordingly, different thicknesses and composition of the formed layer of corrosion products. )
