Like the Critical Pitting Potential experiment (ASTM F746), THE Method involves a Stimulation phase and a Repassivation phase. The THE Repassivation Potential standard technique is run by selecting Experiment > DC… read more →
The data file from a Reactivation experiment is analyzed using the Reactivation.Gscript analysis package provided with the DC Corrosion software. Reactivation experiments are usually used to obtain quantitative sensitization information. In… read more →
Run the Reactivation standard technique by selecting Experiment>DC Corrosion>Electrochemical Reactivation from the Framework™ menu bar. This initiates the following sequence of events: Framework creates a Runner window, and the Electrochemical… read more →
The Reactivation technique is more properly called Electrochemical Potentiokinetic Reactivation, or EPR. It is used to evaluate the degree of sensitization to intergranular stress-corrosion cracking in austenitic stainless steels. The… read more →
Here is a Reactivation Setup dialog box complete with its default parameters. Note that changing a parameter may make quantitative results for the degree of sensitization invalid. Activation Time The… read more →
The RpEc Trend.Gscript data-analysis package provided with the DC Corrosion normally analyzes the data file from a Rp/Ec Trend experiment. The primary use of the analysis packages is to calculate corrosion… read more →
