Original abstract
Recently, the effect of thick boundary films on friction reduction and film forming properties has been studied in detail. This paper is focused on the behaviour of thin viscous boundary films. in the rough surface rolling-sliding point contact operated Changes in film thickness distribution within the lubricated contact between steel ball and glass disc have been observed by thin film colorimetric interferometry using both mineral base oil and mineral oil formulated with non-functionalized polyalkylmethacrylate (PAMA). Obtained results have proved that thin viscous boundary films formed on rubbing surfaces can reduce asperities interactions of rubbing surfaces under very thin film conditions. The beneficial effects on film forming properties have been observed with both real rough and micro-textured surfaces.
