    Influence Of Fluoride On The Electrochemical Behvior Of A New Synthesized Ti-10ta-2mo Alloy For Biomedical Applications
    (University of Eloued جامعة الوادي, 2016-09-01) Sadi Oufella, L.; Benchettara, A.
    The aim of the present study is to investigate the corrosion resistance of a new synthesized Ti-10Ta-2Mo in 0.9%NaCl solution containing different NaF concentrations using electrochemical techniques, including open circuit potential, potentiodynamic polarization, cyclic voltammetry and electrochemical impedance spectroscopy. The results showed that Ti-10Ta-2Mo exhibits a good corrosion resistance in 0.9% NaCl as well as in 0.9%NaCl containing fluoride and even in acidified 0.9% NaCl free of fluoride ion. Very low corrosion current densities and high impedance values were obtained, indicating the passive behavior of the alloy. An active state was observed in acidified 0.9%NaCl of pH 2 in the presence of fluoride. The results showed that Ti-10Ta-2Mo is more appropriate than some materials cited in the literature, suggesting its suitability for biomedical applications.
