摘要	Magnesium and its alloys are very chemically active metals. Oxide film can be spontaneously formed on their surface in an ambient atmosphere. The oxide film on the surface of Mg-8Li alloy was characterized by X-ray photoelectron spectroscopy (XPS) analysis and electrochemical measurements. The results indicated that the surface oxide film formed in the air exhibited multiple layer structure, which consisted of the elements of Li, Mg and O. The concentrations of Mg decreased and Li increased from the bottom layer to top layer of the oxide film. Lithium oxides mostly enriched in the outer oxide layer. The more the potential deviated from the E(corr), the more severe the oxide film was destroyed. Below the film breakdown potential, the surface oxide film can slow down the corrosion of Mg-8Li alloy.
