Localized corrosion, including crevice corrosion, is a leading cause of corrosion-induced failures. THE Method (Tsujikawa-Hisamatsu-Electrochemical Method) has been proposed to measure crevice-corrosion repassivation potentials. This protocol for studying the repassivation… read more →
Here is a THE Repassivation Potential Setup dialog box with its default parameters. Initial E Starting point for the potential sweep during data-acquisition. The allowed range is ±10 volts with… read more →
The data file from a Polarization Resistance experiment is analyzed using the Repassivation Potential.Gscript provided with the DC Corrosion software. It provides plot of current and potential versus time similar… read more →
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 >… read more →
Here is an Rp/Ep Trend dialog box complete with its default parameters. Most of the fields are identical to those found in the Polarization Resistance Experiment. Repeat Time The time… read more →
Run the Rp/Ec Trend standard technique by selecting Experiment > DC Corrosion > Rp/Ec Trend from the Framework™ menu bar. This initiates the following sequence of events: Framework creates a… read more →
This experiment allows you to follow changes in the corrosion rate of a sample versus time. The Rp/Ec Trend script makes a series of polarization resistance measurements at fixed time-intervals.… read more →
The runtime control consist of the standard three buttons and a Display pull-down control. The function of the Skip button differs slightly from that in other DC Corrosion techniques. If you… 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… read more →
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 →
