Abstract

Step-polarization impedance spectroscopy is a technique which can sensitively measure the electrochemical behavior of oxide film alloys. The technique was used to study the behavior of Co-Cr-Mo alloy in solutions representative of physiological solutions. The impedance behavior and polarization behavior of the oxide films covering the alloys were determined. The current transient response to a step in potential contained all the information about film growth, ionic dissolution, and reorganization of the double layer. The technique is more sensitive than either polarization testing or classical impedance testing.
