Abstract
Electrically conductive lubricants offer a variety of benefits for both automotive applications and in the fields of power generation and industrial manufacturing technology. One obvious advantage is their possibility to avoid electric discharges that lead to bearing failures. A further idea is to use the electrical conductivity for the development of functional tribological systems, in which friction, wear and rolling contact fatigue may be influenced by electric fields or electric potentials. The aim of the present project was to develop electrically more conductive lubricants on the basis of ionic liquid additives and to evaluate their potential benefits for different applications. In this paper, we present a selection of results on the synthesis of ionic liquids and electrically conductive lubricants, which need to be non-toxic, miscible and non-corrosive. Moreover results of the investigation of electrically conductive lubricants under the influence of electric potentials are included.
