Thin films of Al-2 wt% Li alloy are prepared on well-cleaned glass substrates by vacuum evaporation at room temperature. Electrical conductivity studies of both alloy Al(Li) and pure Al films show that they obey the logarithmic rate law during the initial period of oxidation. The addition of lithium, however, increases the oxidation rate considerably during the initial period of oxidation. Surface analysis by laser Raman spectroscopy indicates the existence of LiO2 and Al2O3 as the most probable oxide components.
