W artykule zbadano wpływ dodatku cieczy jonowej 1-Butyl-3-methylimidazolium hexafluorophosphate
BMIMPF6 do oleju polialfaolefinowego PAO 8 na właściwości tribologiczne stali. Badania tarciowo-zu-
życiowe zrealizowano na testerze tribologicznym pracującym w skojarzeniu trącym kula–tarcza w ruchu
obrotowym. Testy przeprowadzono przy obciążeniu 10 N na drodze tarcia równej 1000 m. Do badań użyto
tarcz i kul wykonanych ze stali 100Cr6. Badania zrealizowano w warunkach smarowania cieczą jonową
BMIMPF6, olejem poli(α)olefinowym PAO 8, olejem poli(α)olefinowym PAO 8 z dodatkiem 1% oraz 10%
cieczy jonowej BMIMPF6. Po testach tribologicznych zarówno tarcze, jak i kule poddano obserwacjom mi-
kroskopowym – analizowano mikrostrukturę oraz strukturę geometryczną powierzchni w miejscu wytarcia.
Uzyskane wyniki z badań wskazały, że ilość dodatku cieczy jonowej w oleju PAO 8 ma wpływ na właści-
wości tribologiczne stali 100Cr6. Dla 10% stężenia BMIMPF6 w oleju PAO 8 uzyskano większą wartość
współczynnika tarcia o około 26% i mniejsze zużycie tarczy o około 43% w porywaniu ze środkiem smarują-
cym zawierającym 1% stężenia BMIMPF6 w PAO 8. Z kolei porównując zużycie kul, najmniejsze wytarcie
zarejestrowano dla 1% stężenia BMIMPF6 w PAO 8, a największe dla oleju PAO 8.

Abstract: This paper examines the impact of incorporating the 1-Butyl-3-methylimidazolium hexafluorophosphate
(BMIMPF6) ionic liquid into PAO 8 polyalphaolefin oil on the tribological characteristics of the steel-steel
system lubricated with this oil. Friction-wear tests were carried out on a tribological tester operating as a
ball and disc assembly in a frictional motion. Tests were carried out with a load of 10 N over a sliding
distance of 1,000 m. 100Cr6 steel discs and balls were used in the tests. The tests were carried out under
lubrication conditions with the BMIMPF6 ionic liquid, PAO 8 poly(α)olefin oil, PAO 8 poly(α)olefin oil with
the addition of 1% and 10% BMIMPF6 ionic liquid. Following the tribological tests, both discs and balls were
subjected to microscopic observation with a view to analysing the microstructure and geometric structure of
the surface at the wear track. The study found that the quantity of ionic liquid incorporated into the PAO 8
oil has a discernible influence on the tribological characteristics of 100Cr6 steel. Adding a lubricant with 1%
of BMIMPF6 in PAO 8 to PAO 8 containing 10% of BMIMPF6 increased the coefficient of friction value
by approximately 26% and lowered disc wear by approximately 43%. In contrast, the analysis of ball wear
revealed that the lowest level of wear was observed in the 1% concentration of BMIMPF6 in PAO 8, while
the highest level of wear was observed in PAO 8 oil.
