  • Perforation corrosion prediction tool
    Patent number: 6369589
    Abstract: A method for predicting perforation corrosion in a hem flange. The method includes placing an electrode in the hem flange. The electrode extends substantially the entire length of the hem flange. An electrolyte is introduced into the hem flange so that the electrode is immersed, and the electrochemical impedance spectrum of the hem flange is measured. The measured electrochemical impedance spectrum of the hem flange can be compared to a reference electrochemical impedance spectrum. A collection of reference electrochemical impedance spectra can be created by storing the measured electrochemical impedance spectrum of the hem flange.
