“…Results showed that LSP has no significant effect on mechanical properties and wear resistance of Ti-6Al-4V alloys under the same test conditions [291]. In recent years, 3D printing was also used for texturing thermoplastic polyurethanes (TPU) samples [292]. Experiment results exhibited that the spherical-convex textures appeared to facilitate the removal of friction pair debris from the surfaces, reduced the adhesion between the friction pairs and strengthened the wedge effect and cavitation effects of the water flow.…”

The reach of tribology has expanded in diverse fields and tribology related research activities have seen immense growth during the last decade. This review takes stock of the recent advances in research pertaining to different aspects of tribology within the last 2 to 3 years. Different aspects of tribology that have been reviewed including lubrication, wear and surface engineering, biotribology, high temperature tribology, and computational tribology. This review attempts to highlight recent research and also presents future outlook pertaining to these aspects. It may however be noted that there are limitations of this review. One of the most important of these is that tribology being a highly multidisciplinary field, the research results are widely spread across various disciplines and there can be omissions because of this. Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this review. Despite these limitations it is hoped that such a review will bring the most recent salient research in focus and will be beneficial for the growing community of tribology researchers.

“…Their study concluded that compound textures are more beneficial than simple textures in improving the tribological performance of hydrodynamic journal bearings. Similarly, many researchers like Hu et al [85], Kango et al [86,87]  Better to enlarge the slip zone in the axial direction.  For high eccentricity ratio, slip zone location should be 0.9-1.0.…”

Implication of Surface Texture and Slip on Hydrodynamic Fluid Film Bearings: A Comprehensive Survey

Numerous published studies on the non-wettable surfaces with surface texture and slip conditions have been reviewed comprehensively to evaluate the performance of hydrodynamic bearings from last two decades. The recent numerical and experimental studies have been explored to observe the individual and combined influence of surface texture and slip. A variety of texture shapes and optimized slip zone profiles have also been discussed in this article. It has been observed from the literature that a suitable combination of modified slip and the conventional no-slip zone is effective in improving dynamic and static performance of hydrodynamic bearings. Many experimental studies also revealed that micro-scale textures are significantly capable of improving the tribological performance. Moreover, slip boundary condition is more beneficial at low and medium eccentricity ratios.

“…The water‐lubricated bearing often works under varying contact pressures and velocities. Moreover, the lubrication conditions of the water‐lubricated bearing friction pairs are always boundary lubrication or mixed lubrication 29–31 . In order to evaluate the working reliability of the water‐lubricated bearing material, it is crucial to study the water lubrication performance of the material under various working conditions 4,8,32 .…”

Polyetheretherketone (PEEK) is a kind of polymer with excellent mechanical properties combined with good wear resistance and has been widely used in the engineering field. In order to explore the possibility for PEEK using as a water-lubricated bearing material, an in-depth study on the water lubrication performance of PEEK was conducted by using a series of experiments. The water lubrication performances combined with the lubricating mechanism were evaluated both by the friction coefficient and by the wear behavior of PEEK. The results indicated that PEEK was suitable for water-lubricated bearing productions. The water film could form effectively between the friction pairs under high sliding velocity, while the transfer film could form under low sliding velocity. Both the water film and the transfer film could improve the water lubrication performance for the friction pairs. Moreover, sliding velocities and contact pressures highly influence the water lubrication performance of PEEK. The increase in contact pressure or the decrease in sliding velocity would exacerbate the wear of material. The stick-slip phenomena also occurred on the specimens under low sliding velocity. The main purpose of this study is to provide an experimental basis for PEEK using as a waterlubricated bearing material.
