The passive behavior of titanium and its susceptibility to undergo localized attack in different LiBr solutions at 25°C have been investigated using different electrochemical techniques: potentiodynamic polarization curves, potentiostatic passivation tests, EIS measurements and Mott-Schottky analysis. In low and moderately concentrated LiBr solutions, the breakdown potential Eb decreased with increasing bromide concentrations, while in highly concentrated LiBr solutions, Eb increased with increasing LiBr concentration. In the most concentrated LiBr solution (11.42M) Ti did not undergo passivity breakdown even at 9 VAg/AgCl. This observation can be explained by a a decrease in the activity of water in highly concentrated LiBr solutions.
