The data file from an ASTM CPT experiment is identical with one produced by the Cyclic Thermammetry experiment. The data file is analyzed by the Cyclic Thermammetry analysis script.
This experiment is used to evaluate the corrosion tendency of a metal sample as a function of temperature. During the experiment, the specimen is held at a constant potential using… read more →
If your CPT system includes a TDC4 or TDC5 Temperature Controller, it needs to be calibrated before it can be used. Calibration instructions are in the TDC4 or TDC5 Operator’s… read more →
The following figure shows the block diagram for a Critical Pitting Temperature system that uses a TDC Temperature Controller. This figure is the basis of the following discussion. A Gamry… read more →
The Critical Pitting Temperature system includes three techniques that can be used in the study of pitting phenomena. These techniques are highly automated, with the computer completely controlling the data-acquisition… read more →
The Critical Pitting Temperature System is used to determine the temperature-dependence of pitting corrosion. An electrochemical technique measures pitting while the temperature of a metal sample is varied. The pitting… read more →
The final step in the installation is a test that the system has been installed properly. If you have a TDC temperature controller: The following procedure tests a system based… read more →
The following three GAMRY.INI sections describe three different temperature controllers. [TDC_1] LABEL=TDC2 TYPE=2 PORT=1 MODE=COM1:9600,O,7,1 [TDC_2] LABEL=TDC1 TYPE=1 [TDC_3] LABEL=Bath TYPE=3 PORT=1 MODE=COM4:9600,N,8,1 All three sections came from one GAMRY.INI… read more →
The Critical Pitting Temperature software outputs a control bit that you can use to turn a stirrer on and off. This stirrer bit is turned on whenever the system is… read more →
NOTE: The Gamry Framework™ installation program makes the appropriate entries into the GAMRY.INI file. Follow these steps only if you wish to make a change manually. These instructions tell you how… read more →
