in Mo (Table ), forming passive layers, most probably over IMPs. However, the surfaces of 595 AZ31-12Li contained some areas of local corrosion attack around IMPs, which is due to the higher 596 local reactivity of this alloy. Nevertheless, no prominent corrosion attack was observed supporting 597 the high inhibition activity of molybdate. The point EDX analysis (Table ) confirmed the presence 598 of molybdate in the surface layers and the formation of a Mo-rich protective layer over the surface 599 of all examined alloys. The relative Mo/O ratio cannot be estimated from the EDX data since the 600 surface layers also contain hydrated Mg compounds with varying stoichiometry . However, 601 it confirmed that the molybdate inhibitor forms surface protective layers of the surface of AZ31-602 xLi alloys. 603 604 Table . Elemental composition of the surface of AZ31-xLi alloys after 1 and 24 h of exposure to 605 0.05 М NaCl without inhibitor. Point labels correspond to those marked in Fig. Numbers indicate regions analyzed by EDX analysis (Table )
