Temperature-induced structural changes of Organic Friction Modifier films at the iron oxide/oil interface

Abstract: Engine oils provide lubrication to moving components in engines, improving vehicle lifespans whilst reducing emissions and fuel consumption by minimising friction. A common class of friction-reducing additives are Organic Friction Modifiers (OFMs) and these molecules are known to associate with metal surfaces. However, the exact mechanism by which OFMs operate has yet to be precisely defined. To understand how these additives function, a novel tribometer rig has been developed which enables neutron reflectivity experiments to be carried out at elevated temperatures and pressures, whilst the surface is sheared. In this set of experiments, we will measure the conformation of glycerol monooleate molecules on iron oxide surfaces at a range of different temperatures whilst under shear.
