The Effect of Boundary Films on Dented Surfaces Operated under Thin EHD Lubrication
Original language description
The behaviour of thin viscous boundary films in the rough surface rolling-sliding point contact operated under thin film lubrication conditions have been observed by thin film colorimetric interferometry. Changes in film thickness distribution within thelubricated contact between micro-textured steel ball and glass disc were studies with both mineral base oil and formulated oils. It has been shown in the previous studies that the presence of the micro-dent within concentrated contact results in film thickness reduction located downstream of the leading edge of the micro-dent for the operational conditions when the disc is moving faster than the micro-textured ball. In this case such a reduction could cause the local film breakdown of very thin films.Results obtained in this study proved that thin viscous boundary films formed on rubbing surfaces can help to separate rubbing surfaces even under very thin film conditions.
