摘要：

The effect of applied potential and disk rotation speed on the electrohydrodynamic (EHD) impedance of mass-transfer-limited iron dissolution into a 4.0 M FeCl2 electrolyte is presented. The results are interpreted with a model of a duplex film whose growth rate is limited by the flux of chloride ions at the solution-film interface. A combination of EHD impedance and a.c. impedance measurements allows for the determination of both the porosity and thickness of the outer, porous layer.
