The 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.
