For tribological components working under extreme
conditions, such as vacuum, or broad temperature
ranges, it is often a problem to achieve acceptable
durability of their friction parts. Thus, new material
requirements are involved for these tribo-systems, in
particular regarding operability and reliability. At BAM,
several projects were conducted in the recent years,
dealing with the tribological properties of friction
couples at cryogenic temperature and in vacuum
environment. This paper describes the vacuum and ultra
high vacuum tribometers constructed at BAM and
presents experiments carried out with polymer
composites. The experiments presented were performed
with PEEK, filled with solid lubricants, against 304
steel with a pin-on-disc configuration in oscillating
sliding. Friction tests were carried out in vacuum in the
temperature range between -40°C and +160°C and in
ultra high vacuum at room temperature.
