20.500.12556/RUL-106783 Frictional behaviour of imidazolium sulfate ionic liquid additives under mixed slide-to-roll conditions Current work presents the investigation of frictional behaviour of ionic liquid lubricant mixtures under mixed slide to roll ratio. On the contrary to the previous study, which focuses on determination of the most suitable ionic liquid additive for identical ionic liquid weight concentration in lubricant mixture, this work had two scopes. The first one was to determine the optimal chemical composition of ionic liquid additive by investigating the lubricant mixtures with identical molar ratio, and the second one, to optimise additive concentration for certain ionic liquid structure. The changes were observed by two means. Namely, in frictional behaviour, ionic liquid concentration plays significant role. On the contrary, for the mixtures with identical molar concentration, the chemical structures with longer alkyl substituent do not always exhibit improvement. Experiments also revealed correlation between ionic liquid structures, concentration and wear. Atomic force microscopy (AFM) analysis of worn surfaces confirmed the above statements. friction ionic liquid additives MTM AFM trenje ionska tekočina aditivi hrapavost topografija true false false Angleški jezik Slovenski jezik Članek v reviji 2019-03-18 09:16:06 2019-03-18 09:16:07 2025-03-18 10:12:58 0000-00-00 00:00:00 2015 0 0 Str. 489-503 iss. 8 Vol. 27 Dec. 2015 0000-00-00 PreprintVObjavi Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2016-12-31 531.43(045) 0954-0075 10.1002/ls.1292 13929755 2144539 RAZ_Pejakovic_Vladimir_i2015.pdf RAZ_Pejakovic_Vladimir_i2015.pdf 1 6BB88C0417F6092C1829DD50006C8D2F 76eb85a9a8803d32a4d9569e233d0e8453b246b7e82a95f930217d66cf0ee812 5e8c27b4-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=117534 https://onlinelibrary.wiley.com/doi/full/10.1002/ls.1292 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=117533 Fakulteta za strojništvo 0 0 0
