Polarization curves are made by making a linear sweep of the sample’s potential over time. In analytical research fields of electrochemistry this technique is called Linear Sweep Voltammetry (LSV).
Chapter Polarization Curves elaborates on recording and processing polarization curves.
In this extensive section Polarization Curves are discussed. How to setup your equipment, the choice of parameters as well as the data processing is discussed. This will enable you to record a polarization curve and extract the corrosion rate from it by using PSTrace 5. Furthermore, the polarization curves and Evan’s diagrams for passivation films (thick and thin) are discussed. This section closes with a brief description of crevice and pitting corrosion.
