Resumen:
Electrochemical test were performed in simulated body fluid (SBF), in order to evaluate the corrosion resistance of the anodic oxide layers after 24h and 30 days of immersion. After immersion a slight increase in the passivity current density during anodic polarization tests evidences that the SBF exposition produces minor effects on titanium surfaces, and the barrier layer remains effective against corrosion since neither rupture of the film nor localized corrosion occurs. Besides, no significant changes in corrosion barrier effect of the surface films (native or anodised) is evidenced with EIS, in accordance with anodic polarization tests.
