Transport Processes and the Mechanism of Pitting of Metals
TL;DR: In this paper, a pit model was developed on the assumption that the metal ions hydrolyze inside the pits and that the corrosion products are transported by diffusion, and the main reason for passivity breakdown at the initial stages of pit growth was found to be the localized acidification due to metal ion hydrolysis.
