Influence of critical surface defects and localized competition between anodic dissolution and hydrogen effects during stress corrosion cracking of a 7050 aluminium alloy
TL;DR: In this article, it is shown that both anodic dissolution and hydrogen embrittlement operate during the SCC process of a 7050 aluminium alloy stressed in a chloride solution (NaCl 3), and the relative influence of these two mechanisms depends on the main parameters that govern cracking, i.e., the microstructure, the electrochemical potential and the strain rate.

Excimer laser surface treatment of aluminum alloy AA7075 to improve corrosion resistance
TL;DR: The results of the TEM study showed that laser surface melting of the alloy at an intensity of 103 J/cm2 resulted in the elimination of coarse second-phase particles in the laser-melted zone More importantly, two compact layers containing aluminum oxide were formed on top of the lasermelted surface Potentiodynamic polarization tests showed that the corrosion current can be reduced by as much as six times, and a passive region was obtained as discussed by the authors.
