Corrosion mode
The Corrosion mode in PSTrace for corrosion measurements provides some additional measurement techniques:
- Linear polarization, from which the polarization resistance is obtained,
- Tafel plots, from which the corrosion rate is obtained.
When the program is set to 'Corrosion mode', extra tabs called 'Material' and 'Corrosion' are added.
The corrosion mode of PSTrace supports the following methods:
- Linear Sweep
- Cyclic Voltammetry
- Amperometric Detection
- Potentiometry
The polarisation curve is used to calculate the corrosion rate and corrosion potential. This can be done manually by drawing two straight lines as well as by means of a computer fit using the theoretical equation.
