Abstract

The use of impedance measurements, particularly for corrosion studies, is increasing. This paper describes the basic mathematics involved in the modeling and gives some results for the case of steel corrosion in the seawater consisting of 0; 5; 10; 20 and 40 ppm Fe2(SO4)3 or Al2(SO4)3. The data showed that there was an agreement between the corrosion rates calculated by Stern - Geary equation using charge transfer resistance determined from electrochemical impedance spectra and those obtained by weightloss measurements.
