原始语种摘要: Abstract(#br)This article is concerned with an investigation of the tribological performance of magnetorheological (MR) fluids in pure sliding soft-elastohydrodynamic lubrication (EHL) steel/polytetrafluoroethylene (PTFE) point contacts. The lubricating properties of MR fluids were measured in thin film, lubricated conditions using a ball-on-three-plates tribometer and compared to base fluids in the form of Stribeck curves. A range of techniques was employed to interpret the possible mechanisms of friction and wear of dispersed iron microparticles. The friction surfaces were investigated using optical microscopy, environmental scanning electron microscopy (ESEM), X-ray photoelectron spectroscopy, and energy-dispersive spectroscopy (EDS). In all cases investigated, the friction coefficient...
