Impedance of Magnetite-Coated Steel Electrodes

Russian Journal of Electrochemistry Aims and scope Submit manuscript

Abstract

Steel electrodes coated with magnetite of different defectiveness are studied by the electrochemical impedance method. In a borate buffer, the impedance is adequately described by an equivalent circuit for a passive steel electrode. The magnetite coating defectiveness can be evaluated from the frequency peak shift in a Bode diagram.
