Electrochemical Measurement of Corrosion

examples of the electrochemical measurement of corrosion

Potential scans are applied to copper and iron working electrodes in aqueous media using an EA163 Potentiostat.

Regions of immunity, passivation and active corrosion of the electrodes are identified on an i v E plot.
Tafel plots are generated from anodic and cathodic scans starting at the corrosion potential. From these plots the corrosion current density can be determined and hence the rate of corrosion in the particular medium.
