Description	This paper presents an experimental study of the influence of real surface micro-geometry on the film thickness in a circular elastohydrodynamic (EHD) contact formed between a real, random, rough surface of steel ball and smooth glass disc. The Phase Shifting Interferometry has been used to measure in situ initial undeformed rough surface profiles whereas Thin Film Colorimetric Interferometry has provided accurate information about micro EHD film thickness behavior over a wide range of rolling speed. Two real roughness features were studied in detail 56 nm high ridge and 90 nm deep groove, both transversely oriented to the direction of surface motion. It has been shown that ridge is heavily deformed in a loaded contact and its height increases with increasing rolling speed. The asperity tip film thickness behavior is quite similar to the contact average film thickness when the film thickness is higher than the undeformed ridge height. However below this limit the film is thicker than what the EHD the This paper presents an experimental study of the influence of real surface micro-geometry on the film thickness in a circular elastohydrodynamic (EHD) contact formed between a real, random, rough surface of steel ball and smooth glass disc.
