The electrochemical behaviour of the Al2Cu intermetallic compound
TLDR
In this paper, the authors give an extensive electrochemical description of the Al2Cu compound and explain the reported discrepancies, and show that the existence of a passive state is possible at the stability of aluminium hydroxide, copper hydroxides, depending on the potential value and on the pH value of electrolytes.About:

Localized corrosion of 2024 T351 aluminium alloy in chloride media
TL;DR: In this paper, the corrosion behavior of 6056 T6 aluminium alloy was investigated in 1-M NaCl solution and it was found that pits first developed within the grains and grew up through microscopic crystallographic tunnels.

Effects of pH and chloride concentration on pitting corrosion of AA6061 aluminum alloy
TL;DR: In this paper, the corrosion behavior of AA6061 aluminum alloy was found to be dependant on the pH and chloride concentration [NaCl] of solution, and an increase in the chloride concentration slightly shifted both the pitting E pit and corrosion E cor potentials to more active values.

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.

Environmental Factors Affecting the Critical Potential for Pitting in 18–8 Stainless Steel
H. P. Leckie,H. H. Uhlig +1 more
TL;DR: In this paper, the concept of critical potential below which pitting of 18-8 and other passive alloys does not occur in aqueous Cl− media is affirmed, which is interpreted in terms of competitive adsorption of Cl− and other anions for sites on the alloy surface.
