THE INFLUENCE OF ANION TYPE IN IMIDAZOLIUM IONIC LIQUIDS ON TRIBOLOGICAL PROPERTIES
Journal Title: Tribologia - Year 2010, Vol 234, Issue 6
Abstract
This paper concerns research on new, effective lubricant bases that reduce friction and seizure. It is shown, that ionic liquids are substances that influence the reliability and durability of tribosystems. At room temperatures, they are liquids and consist of only ions. Tribological characteristics of three imidazolium compounds differing in anion were researched. Tribological investigation was carried out on a four-ball tester (T-02), steel-steel contact. Motion resistance (friction coefficient) and seizure (wear scar diameter) were analysed. Profiles of balls after tests were also analysed. Ionic liquids researched have better tribological characteristics in comparison to paraffin oil. The lowest (0.08) friction coefficient value was obtained for an ionic liquid containing 3-aminotriazolan anion. It is stated that imidazolium ionic liquids can be an effective base for lubricants.<br/><br/>
