The aim of the present study is to investigate the corrosion resistance of a new synthesized Ti10Ta-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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
