CT3 Low-temperature tribometer
The Low-temperature tribometer can determine the friction and wear behaviour of material pairs within a temperature range of -269°C and room temperature (RT). Pressure can be varied between 10-3 mbar and 20 bar during the tests, independent of temperature control.
This helps to identify optimised friction pairs for the use at low temperatures (e.g. in liquid hydrogen or superconductive systems).
Tests under these conditions indicate that certain polymers and amorphous carbon coatings exhibit lower friction values and less wear at low temperatures than at room temperature.
