Basic aspects when using ionic liquids as a hydraulic fluid

Hydraulic development engineers and tribology specialist still exert substantial effort, time and resources into finding a hydraulic fluid that would be near an ideal fluid. In addition to its basic physicochemical properties, it must meet a number of other requirements related to its practical use within hydraulic system and the materials used therein. Ionic Liquids, as novel lubricants, offer the solution in this regard. The paper gives an overview of the basic properties of selected and tested Ionic Liquids suitable for use as hydraulic fluids. The practically obtained data refer to the basic physico-chemical properties of Ionic Liquids and properties important for practical use within hydraulic system, e.g. compatibility with materials. The results are given in a comparison with common mineral oil based hydraulic oil.
