In order to test the friction and wear behaviour of appropriate solid lubricants and wear resistant material combinations in cryogenic environment, including liquid hydrogen, special test rigs have been constructed. These devices provide test conditions for tribological investigations at temperatures ranging from 4.2K to room temperature in liquid or gaseous environment at pressures between 10-3 mbar and 20 bar. Investigations on polymers, composites and metals with and without coatings show that there is a broad variety of appropriate materials for cryogenic friction units, but the behaviour of austenitic steels in such systems gives an example of non sufficient knowledge in this field.

Because of the extension of applications of low temperature technologies there is a need for investigations in this field. It is the aim to study the stability of the austenitic structure of FeCrNi alloys under these harsh conditions. This paper deals with tribological experiments with alloys of different stability of the austenitic structure in the temperature range between room and liquid helium temperature. It was found that alloys stable at room temperature show martensitic transformation under tribological stressing and decreased service temperature. The obtained transformation behaviour does not exhibit a linear tendency down to liquid helium temperature. A maximum could be stated.
