英文摘要	The corrosion behavior of pure aluminum 1060 subjected to a wet-dry cyclic accelerated test in simulated Nansha marine atmosphere in the dark and under UV illumination has been investigated by means of scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS), and Mott-Schottky measurements in this work. The results show that under the two conditions, the native oxide films are constantly destroyed and the thicknesses of the oxide films continuously decrease in the first 24 days of the corrosion test. In particular, UV illumination can diminish the pitting corrosion susceptibility of the native oxide films to an extent in terms of a photo-induced modification of the native oxide film on the pure aluminum surfaces. Besides, UV illumination can also reduce the carrier concentration in the oxide films, thus reducing the conductivity and the corrosion rate.
