摘要: The electrochemical behaviour of Ti6Al4V, Ti6Al3.5Fe and Ti5Al2.5Fe alloys has been evaluated in Ringer’s solution at 25 °C. effect the substitution vanadium Ti6Al4V alloy specifically addressed. evaluation corrosion resistance was carried out through analysis open circuit potential variation with time, potentiodynamic polarization curves, impedance spectroscopy (EIS) tests. Very low current densities were obtained (order nA/cm 2 ) from curves EIS, indicating a typical passive for all investigated alloys. EIS results exhibited relative capacitive (large resistance) phase angle close to –80° high values 105 Ω•cm medium frequencies, which are indicative formation highly stable film on these solution. In conclusion, is not affected by iron.
