Experimental study of surface texturing effects on Thin Film EHd contacts
Original language description
The effect of surface texturing within thin EHD contacts has been studied by thin film colorimetric interferometry. The behavior of micro-dimples has been observed for conditions when the disc is moving faster than the micro-textured ball. The presence of deep micro-dimples within lubricated contact was found to result in film thickness reduction downstream that can lead to lubrication film breakdown. Conversely, as the depth of micro-dimples is reduced beneficial effect of micro-dimples on film thickneess formation has been observed. Obtained results suggest that surface texturing using appropriate micro-dimples could help to increase lubrication films capabilities even within non-conformal contacts.
