Abstract
Electrochemical impedance spectroscopy (EIS) has been found to be a rapid and accurate technique for measuring corrosion rates in the most difficult situations and for yielding information concerning the occurrence of localized corrosion. When used in the absence of potentiostatic control, the technique carries less instrumental overhead, and the danger of damaging the probe by accidental polarization is reduced. Results from two field tests were presented to illustrate the advantages of using EIS for online monitoring of general and localized corrosion.Keywords
