Challenge to construct new lubrication system focusing on frictional interface structure of ionic liquids

Abstract

Against the background of global environmental problems, there is a need to develop friction reduction technology for machine elements. This investigation focused on the frictional interface structure of ionic liquids is highly dependent on the state of the friction surface. As an experimental method and result, this investigation have succeeded in active control of the friction coefficient in an attempt to control the adsorption structure of ionic liquids by externally inputting an electric potential to the friction surface.
