520			_aTranscripción del resumen del autor: Electrochemical polarization, scanning electron microscopy, and atomic force microscopy (AFM) techniques were used to study the mechanism of cavitation corrosion for anodized aluminum alloy in 3.5% sodium chloride (NaCl) solution. It was found that the anodized film was eroded from the porous outer layer to the dense inner layer under cavitation conditions. AFM images showed that the different phases with different properties were subjected to differing degrees of cavitation, resulting in the formation of a rough cavitation corroded surface. The mean roughness of the corroded surface decreased with increasing cavitation time. The electrochemical corrosion process during cavitation corrosion was controlled by mixed cathodic and anodic processes, and was accelerated by cavitation conditions compared with quiescent conditions.
