The passivation characteristics of tantalum and titanium were studied in various simulated body fluid conditions by means of several electrochemical techniques; open circuit potential vs. time measurement, potentiodynamic polarization, potentiostatic current vs. time measurement, and electrochemical impedance spectroscopy. The polarization resistance was calculated by fitting the impedance data to the equivalent circuit model. The strong passivation was observed for tantalum and titanium at open circuit potential and anodic oxidation potential. The passive currents less than a few tens of μA/cm² were recorded over a wide range of anodic oxidation potential. The impedance data was fitted to the equivalent circuit model R(Q(RW)) and high polarization resistance values were obtained. Although the passivation rate of tantalum was initially lower than titanium, the passive layer became stable as it grew. The passivation rates of tantalum and titanium both increased in the fluid with pH adjusted to 4.5. The passivation rate of tantalum decreased in the fluid containing bovine serum albumin and the passive layer became unstable at anodic oxidation potential, while the passivation rate of titanium increased.
