Abstract
The electrochemical properties of titanium-containing aluminum alloy AB1 in NaCl electrolyte have been studied by a potentiostatic method at a potential sweep rate of 2 mV/s. The results demonstrate that the addition of up to 1.0 wt % titanium increases the anodic stability of alloy AB1 in NaCl electrolyte by 50%. Moreover, with increasing titanium concentration the free corrosion, pitting, and repassivation potentials become more positive. With increasing chloride ion concentration in the electrolyte, the free corrosion, pitting, and repassivation potentials of the alloys decrease, whereas the corrosion rate increases.
