Electrochemical instrumentation used to study corrosion

For information on the electrochemical instrumentation used to study corrosion, please refer to the article Electrochemical kinetics, electrical instrumentation [D 901] in Techniques de l'Ingénieur.

The instrumentation commonly used to study electrochemical kinetics can generally be adapted to the study of corrosion. Equipment used to study the sample at the chosen polarization point (stationary methods or current-potential curves) or to analyze its behavior in the dynamic regime (time recording, voltametry, impedance) can be used in the case of corrosion. Only a small number of specific devices will be presented below (microelectrodes, current noise measurement). As far as cell and electrode geometry is concerned, in addition to the usual configurations (rotating or non-rotating disk...
