A.C. impedance plot often shows rotation of semicircle it, complex plane, i.e. the centre of semicircle locates below real axis. However, the physical causes of that phenomenon are not yet completely clear. One possible cause is the surface roughness of electrode. In regard to metal eleetrods covered with surface film,the film can be considered as dielectric inserted between metal and electrolyte just as the case of a capacitor.

A.C. impedance plot often shows rotation of semicircle it, complex plane, i.e. the centre of semicircle locates below real axis. However, the physical causes of that phenomenon are not yet completely clear. One possible cause is the surface roughness of electrode. In regard to metal eleetrods covered with surface film,the film can be considered as dielectric inserted between metal and electrolyte just as the case of a capacitor. Owing to dielectric dispersion, the capacitance of that capacitor in alternating electric field is a complex parameter C=C′-jC″. Literature data indicated that in the frequency range of a.e. impedance measurement both real and imaginary components of complex capacitance C′ and C″ are independent of frequency. It is postulated that the dielelctric behaviour of that capacitance might be the cause of impedance semicircle rotation. Based on equivalent circuit shown in Figure 4, it could be deduced that the semicircle equation on polar coordinate is ρ =Rt/cosδ cos(θ+δ), and parameters of eqnivalent circuit can be calculated from impedance semicircle according to and C″=C′tanδ, Besides, the apex frequency on semicircle is f~* = fcosδ(ctanθ-tanδ). Above formulae can be reduced to normal semicircle in case δ=0.

Corrosion of steel in concrete is one of the important research:toplcs. Based on the corrosion process, a couple of electrochemical techniques have been tried to measure the corrosion of rebar. This paper reports some preliminary results on it using AC impedance technique. Because the experimental data could not fit the impedance plot of simple equivalent circuit, the authors determined the corrosion of specimens in terms of impedance modulus |Z| instead of the charge transfer resistance usually used. The measurement results achieved in conditions of exposure and environmental chloride content are in good agreement with the gravimetric measurements.
