1. A method for determining the corrosion rates of galvanically coupled metals, said method comprising the steps of:

  • coupling two dissimilar metals;

    using electrochemical impedance spectroscopy to produce a plot of impedance and phase angle verses frequency for the coupled metals;

    matching the coupled metal plot to a known plot for a given physical circuit; and

    determining corrosion rates for the coupled metals based on corrosion rates associated with the matched plot.
