Abstract: The differences between equivalent and real contact configurations of micro-EHL (elastohydrodynamic Lubrication) are analyzed. The influence of material's viscosity on elastic deformation is discussed since it takes time for materials to be deformed. After materials' viscosity is introduced into micro-EHL, a lubricated abrasive wear model is porposed and a criterion for the lubricated wear is given. A lubricated wear example is given to show variations of pressure, film thickness and surface configuration during the wear process.

Key words: Lubricated wear, Visco-elastohydrodynamic
