“…However, the chemical properties of the aluminum metal are active. When the surface of aluminum is exposed in the air, a layer of oxide film will be formed quickly . The oxide film produced naturally is thin, and its corrosion resistance and wear resistance are poor, which can not meet the needs of industry.…”

In this paper, Al 2 O 3 /cerium oxide composite films were prepared on the surface of aluminum by anodic oxidation and chemical solution deposition. The aluminum was firstly anodized in sulfuric acid, then treated with different concentrations of Ce(NO 3 ) 3 · 6H 2 O solution at different temperatures. X-ray diffraction (XRD), energy dispersive spectrometer (EDS), scanning electron microscope (SEM), electrochemical impedance spectroscopy (EIS), and electrochemical polarization tests were used to characterize the properties of the composite films. The results indicate that the Al 2 O 3 /cerium oxide composite films successfully form on 1060Al alloy, and the best condition of film-forming is 2 g/L Ce(NO 3 ) 3 · 6H 2 O and 50°C. Al 2 O 3 /cerium oxide composite film under this condition has a uniform, smooth, and pyknotic surface topography and optimal corrosion resistance. The corrosion density at that time is 1.106 × 10 −6 A/cm 2 and the corrosion potential is −0.458 V.
