Ultra high temperature tribometer
The ultra high temperature tribometer enables the suitability of materials and coatings under dry operational conditions at temperatures of up to 1600°C to be verified experimentally. This testing device and appropriate test procedures can identify material pairs for sliding bearings to ensure that they do not seize up at high temperatures and still exhibit acceptable friction coefficients and wear rates.
Material pairs suitable for use at temperatures of up to 1600°C are required, among other applications, for the control surfaces or body flaps of future space transporters. NASA has in the meantime designated the patented concept of tribologically loaded materials as developed by means of the high temperature tribometer for the X38 spacecraft .
The tribometer can also reliably simulate the friction and wear behaviour of indexable inserts for dry machining.
