A practice of coulometrically evaluating the protectiveness of paint coatings

A Study of the Corrosion Kinetics by Coulometric Detection of Corrosion Products on a Glass Carbon Electrode

“…Hence, by measuring current I(t) and process time t, one can determine with high accuracy the amount of the compound that has undergone electrochemical conversion. If only one electrochemical reaction occurs, its stoichiometry can be quantitatively related to the total electric charge q that passed through the cell in accordance with Faraday's law (1).…”

“…This forces corrosion scientists to use indirect estimation criteria that rely on various concepts of the form of the result to be obtained, what method should be used to obtain the results, and in what form they should be provided for interpretation [1][2][3].…”
