The following important terms are used throughout this help section. Active Cell The cell (if any) currently connected to the system potentiostat. Any electrochemical measurements are made on the active… read more →
This section describes the standard corrosion-measurement techniques that are included with a Multiplexed DC Corrosion system. All of these techniques use an ECM8 Electrochemical Multiplexer to run sequential tests on… read more →
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 a… read more →
The data file from a Tafel experiment is analyzed using the Tafel analysis package provided with the DC Corrosion software. Tafel experiments are usually used to obtain quantitative corrosion-rate information. The… read more →
The Tafel standard technique is run by selecting Experiment > DC Corrosion > Tafel from the Framework menu bar. This initiates the following sequence of events: Framework creates a Runner… read more →
Use the Tafel technique to obtain an accurate estimate of the corrosion rate and beta constants of a metal in a solution. Cell current is measured during a slow sweep… read more →
Here is a Tafel 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 a resolution… 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 →
