Some outstanding grease research carried out by a team of great experimentalists using both the MTM and EHD rigs. The novel methodology employed showed how it is possible to disentangle the behaviour of the grease thickener from that of the base oil, which is then used to explain the characteristic “bump” observed in some grease Stribeck curves. The illuminating research concludes that greases exhibit two distinct operating regions, in terms of friction and film thickness. A must read for anyone involved in this sometimes challenging area of tribology research.
