Abstract: The aluminum-lithium (Al-Li) alloys for aviation are widely used in aerospace industry, due to their low density, high specific strength and specific stiffness, improving the pay load and fuel efficiency of the aircraft. However, the Al-Li alloys are susceptible to localized corrosion. In industry, the corrosion resistance of aluminum alloys is usually improved through anodizing treatments. This paper emphatically studied the influence of oxidation temperature on the structure and corrosion resistance of anodic oxidation film. The anodic oxidation film of 2099 aluminum-lit-hium was obtained by anodic oxidation in tartaric-sulfuric acid solution at 22 ℃, 27 ℃, 32 ℃, 37 ℃, 42 ℃ and 47 ℃, respectively. The morpholo-gy of the anodic films was examined using field emission gun scanning electron microscope (FEG-SEM). The corrosion resistance of the anodic films was investigated through electrochemical impedance spectroscopy (EIS) and neural salt spray test (NSST). The results show that, as anodizing temperature rises, the film growth rate and total film thickness increased,and the dissolution and film porosity increased, when the temperature is higher than 37 ℃, rod-shaped cavities with their distribution consistent with that of T1 phase appeared. The corrosion resistance of the TSA film generally increased firstly and then decreased in the range of test temperature.
