The electrochemical behavior of the third generation Al-Li alloy 2098 was investigated with a fundamental approach, where experimental results were theoretically analysed in terms of the Point Defect Model (PDM). For this purpose, the AA2098-T851 was tested in NaHCO3 solution under a CO2
Atmosphere to investigate the kinetics of formation and breakdown of the protective passive film. Experiments were performed at potentials where both metal dissolution and the hydrogen evolution reaction (HER) occur.
