Resumen
Ionic liquids have shown an outstanding performance as lubricants in different
contacts. Protic ammonium carboxylate ionic liquids (PILs), both neat and as
additives in water, are being studied as friction-reducing and wear prevention
lubricants in stainless steel-sapphire contacts.
When a PIL was used as additive in water, the high temperature reached at the
sliding contact produced the evaporation of water and the formation of a low friction
PIL boundary layer.
In the present study, the formation of the PIL boundary layer on AISI316L stainless
steel under static conditions is described and its lubricating performance against
sapphire balls has been studied. The effect of relative humidity has been studied
using a vacuum chamber.
The results described in the present study show a good tribological performance of
these thin surface films, in pin-on-disc tests, reducing the running-in period of high
friction coefficient, preventing wear and reducing the volume of lubricant ...
