Abstract

This study describes the effect of textured patterns on the lubrication performance in starved hydrodynamic lubrication. A friction test rig including an in-situ observation system is used with controlled lubricant quantity to create point contact between a convex glass lens and rotating steel disc. The in-situ observation system captures the meniscus pattern around the lubricated area as well as optical interferograms of the film thicknesses. Longitudinal or transverse grooves are created on discs, which improve lubricant supply into the lubricated area at high sliding conditions, compared to a flat disc. Mechanisms for improving the lubricant supply through textured patterns are discussed based on the in-situ observation results.
