| 中文摘要 | Five room temperature ionic liquids (ILs),1-butyl-3-methylimidazolium hexafluorophosphate (L-P104), 1-hexyl-3-methylimidazolium hexafluorophosphate(L-P106), 1-octyl-3-methylimidazolium hexafluorophos-phate (L-P108), 1-decyl-3-methylimidazolium hexafluoro-phosphate (L-P110), and 1-hexyl-3-methylimidazoliumtetrafluoroborate (LB106) were studied as 1 wt% additivesof polyurea grease for steel/steel contacts. Their tribologicalbehaviors as additives of polyurea grease for steel/steelcontacts were evaluated on an Optimol SRV-IV oscillatingreciprocating friction and wear tester and an MRS-1J (G)four-ball tester at room and high temperatures. The frictiontest results showed that the ILs, as 1 wt% additives inpolyurea grease for steel/steel contacts, had better frictionreduction and anti-wear properties at high temperature thanat room temperature, and ILs can significantly improve thefriction reduction and anti-wear properties of polyureagrease compared with base grease containing 1 wt% of zincdialkyldithiophosphate (T204). The excellent tribologicalproperties are attributed to the formation of a surface pro-tective film composed of FeF2, nitrides, and compoundcontaining the P–O bonding on the lubricated metal surfaceby a tribochemical reaction. The ordered adsorbed films andgood miscibility of ILs with the base grease also contributed to the excellent tribological properties. Wear mechanismsand worn steel surfaces were studied by a PHI-5702 mul-tifunctional X-ray photoelectron spectrometer and a JSM-5600LV scanning electron microscope. |
