“…They have wide applications in automobile, marine, aerospace, machine tools and other fields [1]. However, existing designs experience several failures like wear, cavitation, high friction and less lubricant supply [2], which decreases the load bearing capacity (LBC) of the slider bearings. To date, several studies [3,4] have been reported to enhance the tribological performance of the slider bearings by reducing frictional wear.…”

The present numerical study investigates the thermohydrodynamic performance of inclined/convergent slider bearings using different placing of textures and slip region. Mass-conserving Elrod cavitation model with slip boundary is used to analyze the static performance variables. Due to better fluid retain-ability, Square-shaped micro-textures have been used. The slip coefficient for the slip boundary on the bearing surface is taken as 9 μm. As reported previously for convergent bearings, the optimal convergence ratio (K) value for maximum bearing performance lies between 1 and 1.4. Therefore, in the present paper, the value of K is taken as 1.2. It was observed that the location of micro-textures and slip boundary greatly influence the bearing performance. When textures and slip regions are placed near the inlet region of the bearing, with a reduction in shear stress and the availability of the lubricant near the inlet, the resistance to the lubricant flow reduces, increasing lubricant intake. Further, for partial slip bearing, an abrupt obstruction to the lubricant flow occurs at the location of the slip/no-slip interface, which increases the hydrodynamic pressure and improves the load bearing capacity of the bearing. Moreover, due to less friction observed, various slip-textured bearings showed a reduction in the average lubricant temperature compared to conventional bearing. In the end, an updated combined slip-textured bearing surface is presented for maximum bearing performance in terms of different performance variables. The findings of the current work would be helpful for researchers in selecting the optimum slip-textured surface for inclined slider bearings under the current operating conditions.

“…Surface texture technology is one of the methods for surface modification, which improves the performance of friction pairs by preparing concave and convex bodies with specific parameter distribution, position arrangement and geometric morphology on the surface of materials [1][2][3]. Its mechanism of action is to use the characteristics of micro-concave-convex textures to accommodate wear particles [4,5], store lubricating media [6,7], and generate the dynamic pressure effect under various lubrication conditions [8].…”

To improve the friction performance of the friction pair of the hydrostatic thrust bearing, the surface with convex textures is designed at the bottom of the oil cavity. The result shows that the oil cavity with the convex structures can significantly improve the friction characteristics of the hydrostatic thrust bearing. To further study the effect of texture parameters (texture radius, texture spacing and texture quantity) on its performance, the method based on the full factor test is used for single objective optimization, and the methods based on the BBD response surface and the NSGA-II algorithm are used for multiple target collaborative optimization. The full factor test with the main effect shows that the best combination with the bearing capacity is 0.5 mm, 7 mm, 7 and 4.91%, and the best combination with the rigidity is 0.3 mm, 5 mm, 5 and 3.61%. The influence of textures on the maximum temperature of oil film is basically unchanged and the bearing capacity is inversely proportional to the friction factor. When considering the interaction between texture parameters, the BBD response surface method is used for multi-objective optimization. The result shows that when the texture radius is 0.7 mm, the texture spacing is 7 mm, the quantity of textures is 6.2, and the area ratio is 8.73%, the optimal response values can be obtained, which the bearing capacity is 8519.31 N and the rigidity is 1.31868 E+12 N/m. The multi-objective optimization analysis of the NSGA-II algorithm based on the BBD response surface model shows that the algorithm can obtain a Pareto solution set. Each set of solutions obtained by the NSGA-II algorithm is the optimal solution. Both the BBD response surface method and the NSGA-II algorithm can be used to solve multi-objective problems.

“…[21,22] In addition, it has been proved that textures and lubricant coatings can synergistically improve the tribological properties of surfaces. [23,24] Parameters such as density, depth, and shape of the textures have impacts on the synergistic improvement.

Ultrasonic surface rolling processing (USRP) is used to fabricate textures with different shapes and processing times on the surface of GCr15 substrates. The PTFE‐PPS/SiO2 lubricant coating is subsequently deposited on texture surfaces by electrohydrodynamic atomization (EHDA). USRP texturing not only forms the texture shapes, but also realizes the strengthening effects of increased hardness and residual stress. Synergistic effects of the PTFE‐PPS/SiO2 coating and different USRP textures on dry friction and wear properties are investigated. The results show that the synergistic effect of the linear texture with two processing times and the PTFE‐PPS/SiO2 coating achieves better dry friction and wear performance than the individual effect. The texture shape and the processing times both affect the synergistic effect. The increase in processing times has a positive effect on synergistic improvement. The linear texture plays a better synergistic effect compared with that of the wavy texture with the same processing times. The USRP textures affect the tribological properties of texture‐coating samples by mainly influencing the coating‐substrate adhesion. The texture with an appropriate shape and height can improve the adhesion with the coating, and thus synergistically improve the dry friction and wear properties of the substrate.This article is protected by copyright.
