| Résumé : |
The corrosion behavior of Ti–5Ag–xFe alloys (x = 1, 2.5, 5 wt%) in neutral saline solution was investigated by the open-circuit potential (OCP), potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and potentiostatic tests. The microstructural observation indicated that β-Ti phase was retained by the addition of Fe into Ti–Ag alloys. Compared with commercially pure (CP) Ti, Ti–5Ag–xFe alloys exhibited higher corrosion potentials, lower current densities, and larger impedance, these suggested that Ti–5Ag–xFe alloys have nobler electrochemical corrosion behavior when compared with CP Ti in neutral saline solution.
