PapersEffect of water on the interfacial structures of room-temperature ionic liquidsIn refereedShouhei Kawada, Eri Kodama, Keisuke Sato, Shuhei Ogawa, Masaya Watanabe, Hikaru Okubo, Shinya SasakiSURFACE AND INTERFACE ANALYSIS51,1,17-202019/1～10.1002/sia.65360142-2421The interfacial structures of cyano-based room-temperature ionic liquids play a very important role in reducing friction. However, the presence of water impairs their tribological performance. The interfacial structures and friction forces of 1-ethyl-3-methylimidazolium dicyanamide, [EMIM][DCN], and the effect of water on these structures and forces were investigated using atomic force microscopy. In addition, the interaction of water and [EMIM][DCN] was evaluated using Fourier-transform infrared (FT-IR) spectroscopy. Multiple repulsive layers were observed in the [EMIM][DCN] solution. This solution showed low friction force because these repulsive layers worked as protective layers against friction. On the other hand, the specific repulsive layer characteristics of [EMIM][DCN] could not be observed in a [EMIM][DCN] + 2 wt% H2O solution. FT-IR results indicated that the layer structure of [EMIM][DCN] was disturbed by the addition of H2O. Therefore, the solution containing water exhibited a high friction force.

PapersTribological Performance of Halogen-Free Ionic Liquids in Steel-Steel and DLC-DLC ContactsIn refereedHikaru Okubo, Shohei Kawada, Seiya Watanabe, Shinya SasakiTRIBOLOGY TRANSACTIONS61,1,71-792018～10.1080/10402004.2016.12727311040-2004The tribological performance of halogen-free ionic liquids at steel-steel and diamond-like carbon (DLC)DLC contacts was investigated. Hydrogenated amorphous carbon (a-C:H) and tetrahedral amorphous carbon (ta-C) were used as test specimens. Friction tests were carried out on steel-steel, a-C:H-a-C:H, and ta-C-ta-C contacts by using a reciprocating cylinder-on-disk tribotester lubricated with two different types of halogen-free ionic liquids: 1-ethyl-3-methylimidazolium dicyanamide ([BMIM][DCN]) and 1-butyl-3-methylimidazolium tricyanomethanide ([BMIM][TCC]. From the results of friction tests, the ta-C-ta-C tribopair lubricated with [BMIM][DCN] or [BMM][TCC] exhibited an ultralow friction coefficient of 0.0180.03. On the other hand, ultralow friction was not observed at the steel-steel and a-C:H-a-C:H contacts. Measurements obtained with a laser scanning microscope and an atomic force microscope (AFM) showed that a chemical reaction film, derived from the ionic liquid lubricant used, was formed on the steel surfaces. However, this chemical reaction film was not observed on either of the DLC surfaces. The AFM results showed that there were high-viscosity products on the ta-C surfaces, that the wear tracks on the ta-C surfaces exhibited low frictional properties, and that the ta-C surfaces were extremely smooth after the friction tests. Based on these results, it was concluded that an ionic liquid-derived adsorbed film formed on the ta-C surface and resulted in the ultralow friction when lubricated with a halogen-free ionic liquid.
