Abstract
The purpose of this study was to investigate the effect of fluoride and eugenol concentration on the corrosion behavior of titanium (grade 2) alloy in artificial saliva using potentiodynamic polarization and spectroscopy impedance. Chemical analyses of the surface were characterized by SEM. The results showed that either the NaF or the presence of eugenol in medium saliva had a significant influence on the corrosion rate (Jcorr) and polarization resistance (Rp): the Jcorr value increased and Rp decreased in medium containing fluoride, but the presence of eugenol in media improved the corrosion resistance of this alloy.
