Some innovative surface texturing techniques for tribological purposes

When a textured ring rotates relatively against the other texture-free ring in a parallel thrust bearing, cavitation of liquid lubricant may occur in the divergent zones of the dimples or grooves on the textured surface due to local pressure drops. The Reynolds and Jakobsson–Floberg–Olsson (JFO) models are two widely used cavitation models in hydrodynamic lubrication theory, where the former lacks mass conservation while the latter enforces it. In order to investigate the applicability of the two models to the hydrodynamic lubrication analysis of parallel thrust bearings with surface textures, comparison between experiment and simulation results has been carried out on parallel thrust bearings in terms of cavitation zone morphology in a groove, friction coefficient, and bearing clearance. The results have shown that the observed cavitation morphology in steady state is more similar to the prediction from the JFO model than that from the Reynolds model.

Direct Observation of Cavitation Phenomenon and Hydrodynamic Lubrication Analysis of Textured Surfaces

Benefits of surface textures for improving the performance behaviors of tribo-contacts are being explored and established by the investigators across the globe. But the consolidated information of findings of such explorations are spread. Therefore, the objective of this paper is to summarize the information available related to the preparation of surface textures and performance outcomes in the presence of surface textures at the concentrated contacts. Mainly, recent research findings and practices followed for the study of friction, wear, lubrication, contact fatigue, vibration, and noise at the generic concentrated contacts in presence of surface textures are reviewed for current status of research in the area and outlining the future prospects.
