Effect of Benzotriazole on Corrosion Resistance of Al2O3/Cerium Oxide Composite Films on the Al Surface
Al2O3/cerium oxide composite films were prepared on the surface of aluminum by an anodic oxidation and chemical conversion method. The aluminum was firstly anodized in sulfuric acid, and then the anodized aluminum was treated with the Ce(NO3)3 solution. The effect of different concentrations of 1H-Benzotriazole (BTA) on the corrosion resistance of Al2O3/cerium oxide composite films was investigated. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM) with energy dispersive spectrometer (EDS), and electrochemical workstation were used to characterize the properties of the composite films. The results show that the deposition effect of cerium ions is optimal in 0.5 g/L BTA. At the same time, the surface uniformity and smoothness of the composite films are both enhanced. And the corrosion resistance of the composite film is strengthened.
