Ionic liquid (IL) lubricants with low friction, excellent wear prevention properties (equivalent to formulated engine oil), and excellent lubricity on noble metals and silicon, as well as on ferrous and non-ferrous metals, are presented. Wear prevention by IL was strongly dependent on the cation. Room temperature IL (RTIL) with non-imidazolium cations prevented wear of steel much better than any imidazolium salt. Several new RTIL, without anti-wear additives, gave extremely low wear of steel, comparable to fully-formulated engine oils. The best imidazolium salts had wear an order of magnitude greater than the most effective new RTIL. All IL had friction coefficients lower than all conventional lubricants not containing friction modifier additives. This is an abstract of a paper presented at the World Tribology Congress III (Washington, DC 9/12-16/2005).
