Study of the Effect of Inhibitor on the Corrosion Behavior of Steel Using Chebyshev Noise Spectroscopy and Electrochemical Impedance Spectroscopy


The electrochemical noise of a system of two identical steel electrodes in the NaCl solution without and with an addition of benzotriazole (BTA) corrosion inhibitor is measured and analyzed. It is shown that this method is a convenient tool for testing the protective properties of inhibitor. The method of impedance spectroscopy applied to this electrochemical system gives the information on the mechanism of inhibitor action.
