Electrochemical Stability and Biofouling Behavior of Differently Polarized Ti Surfaces in Simulated and Natural Seawater

The electrochemical behavior of titanium (Ti) was investigated before and after anodic polarization at different potentials in simulated seawater solutions. The results showed that the Ti anodically polarized at 3.2 VSCE was much more stable than those at 0.5 VSCE and the open-circuit potential (OCP), and the passive film formed at the low potentials could be transformed to a more protective film after polarization at the high potential. The...
