Description	This paper focuses on the effects of surface topography modifications on lubrication film thickness within non-conformal lubricated contact. Optical test rig is used to study the lubricant film behavior between the flat surface of a chromium coated glass disc and a steel ball. An array of micro-dents was produced on the ball surface to be able to demonstrate the effect of surface topography on lubrication film formation. Experiments were carried out under elastohydrodynamic and mixed lubrication using steady state and transient operational conditions (start up and reversal motion). Obtained results have shown that surface texturing could represent the way how to increase lubrication efficiency of rolling/sliding non-conformal contacts under operational conditions when lubrication film is not able separate rubbing surfaces. Lubricant emitted from the micro-dent helps to reduce the asperities interaction. Moreover, the effect of surface micro-cavities has been observed within starved non-conformal conta This paper focuses on the effects of surface topography modifications on lubrication film thickness within non-conformal lubricated contact.
