Abstract
The paper is focused on the influence of surface texturing in non-conformal contacts on lubricant film thickness, contact pressure and rolling contact fatigue (RCF). Both the possible negative and positive effects of surface texturing are considered. The lubricant film thickness was measured using experimental apparatus based on thin film colorimetric interferometry, where the contact is realized between steel ball and glass disc. The RCF test rig consists of two discs loaded and running against roller specimen. The test results show that shallow micro-dents could be considered as beneficial to improve RCF of machine parts under mixed lubrication.
