The potentiostatic technique examines the behavior of a system when held under a constant potential control. The graphical output of the experiment is a plot of current vs. time. Analysis… read more →
Here is a Potentiostatic Setup dialog box complete with its default parameters. Initial E The potential prior to any potential step. The allowed range is ±10 V with a resolution… read more →
The data file from a Potentiostatic experiment is analyzed using the Potentiostatic.Gscript analysis package provided with the DC Corrosion software. Potentiostatic experiments are usually used to obtain quantitative information. The primary… read more →
Run the Potentiostatic standard technique by selecting Experiment> DC Corrosion>Potentiostatic from the Framework™ menu bar. This initiates the following sequence of events: The Framework creates a Runner window, and the… read more →
Description The Quick Integrate command integrates the current to achieve a total charge value. This command requires you to select an X Region. The command operates on all visible traces,… read more →
Description Simple EPR calculates a degree of sensitization to Intergranular Stress Corrosion Cracking in heat-affected stainless steels. This command is only available in the Reactivation Analysis package. You can find… read more →
Description The Tafel Fit command is used to calculate a corrosion rate from Tafel or potentiodynamic data. Tafel analysis assumes that the corrosion reactions are under kinetic control. See the… read more →
Description The E Log I Fit is a classical Tafel analysis done using only one side only using one side (anodic or cathodic) of the log(I)-versus-E curve. It assumes that… read more →
Description Min/Max determines the minimum and maximum current. This command requires that you select an X Region. The command operates on all visible traces, and the results are placed on… read more →
