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 E b decreased with increasing bromide concentrations, while in highly concentrated LiBr solutions, E b increased with increasing LiBr concentration. In the most concentrated LiBr solution (11.42M) Ti did not undergo passivity breakdown even at 9 V Ag/AgCl . This observation can be explained by a a decrease in the activity of water in highly concentrated LiBr solutions.
