However, the effect of the change in contact geometry has not been fully realised. In this paper, a series of running-in tests on a Si 3 N 4 ball and a WC plate have been performed in glycerol-water mixtures with different concentrations. The shape of the wear scars and the chemical compositions of the worn surfaces were characterised in detail. A numerical EHD and mixed lubrication model was established to comprehensively analyze the effects of geometric profiles, surface roughness, and working / lubrication conditions on ultralow or super low sliding friction. The experiment and simulation results of the study have provided an in-depth understanding of the mechanism of super low friction of liquid lubricated sliding point contacts. running-in super low friction contact geometry silicon nitride tungsten carbide glycerol-water Full Text Additional Declarations No competing interests reported.
