In the paper the investigative results of lubricity and surface properties for four synthetic perfluoropolyether (PFPE) oils, comparing with the high quality gear oil Mobilube 1SHC 75W-90 and two base oils PAO-6 and SN-650, are discussed. The goal of the research was to identify anti-wear and anti-seizing properties of PFPE oils correlation with their surface-energetic and viscosity-temperature properties. Modern test equipment was used for perfomed research. The following apparatuses were used: KSV Sigma 701 and KSV CAM 100 made in Finland, AMVn Anton Paar made in Austria, and T-02 four-ball apparatus made in Poland. Measurement of density, surface tension and wetting angle were done with the use of KSV Sigma 701 apparatus, according to its instruction manual. The static wetting angle on the real surface of a steel plate was determined with the use of KSV CAM 100 apparatus. The dynamic viscosity of the tested compounds was determined with the use of AMVn microviscometer. The tests of the lubricity properties of the synthetic oils and comparative liquids were perfomed with the use T-02 four-ball tester. The investigative results showed that PFPE oils can be used particularly in hydrodynamic and elastohydrodynamic lubrication.

The paper discusses the results of the studies on the surface properties and lubricating abilities of five ionic liquids compared to a high quality gear oil: Mobilube 1SHC 75W90 and two base oils: PAO-6 and SN-650. The investigated ionic liquids were: 1) tetrafluoroborate 1- benzyl-3-methylmidazolium, 2) bis (trifluoromethylsulfonyl) imide 3-methyl-1- propylpyridinium, 3) bis (trifluoromethylsulfonyl) imide 1,2-dimethyl-3-propylimidazolium, 4) bis (trifluoromethylsulfonyl) imide trihexyltetradecylphosphonium), 5) tetrafluoroborate trihexyltetradecylphosphonium. The density, surface tension and wetting angle as well as dynamic and kinematic viscosity were measured. Next, the lubricity properties were evaluated using the four-ball tester. The research results showed the more better lubricity properties of ionic liquids than the base oils. The research results showed the more better lubricity properties of ionic liquids than the base oils. The ionic liquids had the comparable properties to a high quality gear oil. Obtained results of these preliminary studies confirmed a possibility of using selected ionic liquids as new lubricants. These compounds can probably replace the lubricants used so far and find a wide scope of application in lubrication technology in the future. However, particular implementations require further complex studies.
