    Abstract

    Experimental aspects of making corrosion rate measurements with the electrochemical frequency modulation technique (EFM) have been discussed. Corrosion rate and corrosion kinetic parameters can be obtained without prior knowledge of the Tafel slopes. Several cases were considered using a dummy cell designed to mimic a corrosion reaction. These approaches were then applied to copper, zinc, and carbon steel samples and the results were compared to more traditional electrochemical techniques like polarization resistance and electrochemical impedance spectroscopy. Good agreement has been observed between traditional methods and EFM.
