...A simplified equivalent circuit consisting of the solution resistance (R_s) connected in series to the polarization resistance (R_p) which is in parallel with an effective capacitance (C_eff) was assumed for modeling the spectra from the EIS, as shown in Figure 5...

...Abstract The capacitances of passivated electrodes were investigated to aid in explaining the effect of capacitive discharging during scribing of rotating cylindrical electrodes. In scribing experiments, a capacitive current is associated with the transient current response which results from...

... anticorrosive coatings corrosion vinyl coatings electrochemical impedance capacitance high frequency INTRODUCTION The pipes and infrastructure for conducting water for human use need anticorrosive protection. In spite of this, paint coatings used in those systems must fill very special features, which can...

... and does not contain elevated levels of cathodic depolarizers. Development of ennobled potential is observed to correlate with E_corr near beginning of exposure and occurs on surfaces exhibiting as little as 20% biofilm coverage. Galvanostatic measurements of coupon capacitance reveal a strong...

...In the examples chosen, the major effect on the development of the current distribution is the time response of the interfacial surface capacitance. The magnitude of the capacitance as well as the frequency and corresponding time dependence is easily measured, and predictions can be made as to when...
