An overview of micro-tribological events, including micro-adhesion, micro-hysteresis and micro-lubrication is presented in this paper. The link between micro-lubrication and elastohydrodynamics is inseparable, but it appears that elastomer properties have diminishing importance as the scale of texture reduces. In the limit, micro-hysteresis effects give way to micro-adhesion, the latter depending critically on the harshness of micro-texture. Lubricant entrainment over asperity peaks is a function primarily of macro-texture, in particular the slope of such asperities and the void volume created by the macro-texture. This void volume acts as minute lubricant reservoirs which supply the entrainment mechanism and ultimately oppose the adhesion-generating harshness effect. There has been a limited investigation as reported in the literature of the macro-tribology of elastomeric contacts, but very little in the case of micro-events. This is surprising in view of the crucial relevance of such phenomena to an understanding of sliding seals, rubber mounts and tyre friction.
