The surface roughness of two contacting surfaces significantly influences thetribological performance of the mechanical elements. Their impression is morepronounced under the mixed elasto-hydrodynamic lubrication condition. The camand flat follower mechanism is a typical sample in which adverse tribologicalconditions, including direct boundary interactions occurs. In this study, effects ofsurface roughness on the friction force and friction coefficient are investigatedusing engine oil at different test conditions in a cam follower mechanism. It isseen that decreasing roughness of the contact surfaces has a more desirabletribological performance, and decrease friction coefficient, therefore increasewear resistance.
