Determination of Organic Friction Modifier conformation under shear

Abstract: Engine oils act to lubricate and protect moving parts in an engine. They act to reduce friction and reduce emissions. A major class of friction reducing additives are organic friction modifiers (OFMs) and these molecules are known to associate with the metal surfaces, although their exact conformation remains unknown. To answer the question about OFM conformation, we have commissioned a new tribometer rig which allows neutron reflectivity experiments to be carried out, at elevated temperatures and pressures, whilst the surface is being sheared. In this set of experiments, we will measure the conformation of glycerol mono-oleate molecules on iron oxide surfaces at a range of shear rates for two different pressures.
