Electrochemical Cell + Tribometer Combination
Tribocorrosion Test Modes
- Scratch Adhesion
To investigate synergy of wear and corrosion of steel, the tests were carried out under cathodic and no cathodic protection conditions. We conducted 3 different load conditions (10, 100, 200 N at 2 Hz sliding frequency) at 70°C. The electrochemical polarization tribocorrosion tests were performed with a standard Ag/AgCl reference electrode and a platinum counter electrode.
OCP – Oper Circuit Potential (Ecorr)
The plot below shows the open circuit corrosion potential, Ecorr obtained from the integrated potentiostat.
The figure below shows the wear rate difference between the cathodic and non cathodic polarization conditions. The difference of the wear rate shows the synergy of the chemistry used during the test.
This corrosion tribology testing showed the importance of tribocorrosion studies. The wear loss rate attributed between mechanical vs mechanical + corrosion test was significantly different.
