English abstract:
In this paper, it is shown that specific ionic liquids have great potential to be used as additives for tribological applications. The results promise a high load calTying capacity; especially for the cation 3-0cthylthiazolium and long term stability up to temperatures of 120°C is given. However, only extreme pressuresl anti-wear properties are examined in detail with the selected test method. Fliction modifier (FM) effectiveness cannot easily be demonstrated, because of the good performance of the selected base stock. Nevertheless, ionic liquids in general did not change the FM characteristic of the base oil in a negative way. A promising potential for ionic liquids to replace a majority of additives in tribological systems is given. Methods used are Schwing-Reib-VerschleiB test according to DIN ASTM D 5706, and Four Ball Tests
according to DIN 51360. Mechanisms related to additives in lubricants are investigated by X-ray photoelectron spectroscopy.
