dc.description.abstractThe scanning microreference electrode (SMRE) technique and scanning electron microscopy (SEM) were applied to investigate the localized corrosion in its early stage of Al 2024-T3 alloy. SMRE potential measurements revealed that localized corrosion occurred on the alloy surface immediately after the exposure to 0.01 mol . L-1 NaCl solution at open-circuit potential, which was more negative than the pitting potential. The potential peaks developed with time and reached the maximum after 2 h exposure. Consequently, the heights of potential peaks would decrease and then maintained a stable value for a long time. SEM indicated the initial of localized corrosion was associated with the second phase particles, especially the Al2CuMg (S phase). Three types of corrosion behavior of S phase were observed.zh_CN
