Abstract
Abstract Aiming at a better understanding of the structure-function relationship of the molecular structure, corrosion and lubrication properties of ionic liquids (ILs), three 2-mercaptobenzothiazole functionalized {ILs} were synthesized and their corrosion and lubrication properties were investigated. Results of electrochemical and tribological experiments indicated that the functionalized {ILs} showed much lower corrosivity and better lubricity for bronze than conventional {ILs} [BMIM][BF4]. And the investigation revealed that {ILs} with lower corrosivity promised the better lubrication properties via reducing the severe corrosive wear. Results from the surface analysis by {XPS} and SEM-EDS suggested that the anti-wear and friction-reducing mechanisms of the functionalized {ILs} were ascribed to synergistic effect of adsorbed {ILs} film and tribochemical products formed on the worn surfaces.
