“…It is also necessary to mention that, there is a limit to the action depth threshold for the supplementary effect of micro-bearings on grease. This does not make the pit very visible and leads to a decrease in the dynamic pressure lubrication performance of surface lubrication film [28].…”

Joint bearing contact surfaces of high-tech precision machinery applied particularly in the manufacturing industry undergo varying range of extreme temperature and pressure conditions, which subject them to frictional wear, tear and stress during operation in different environments of application. A continuous assessment of their resilient capacities is therefore necessary to avoid operational failure of core base component parts. The aim of this study is to assess the effects of multi-surface treatment and texturing processes on the frictional and stress performance of aluminum based self-lubricating joint bearing under grease condition. Using ANSYS software based on the Hertz contact theory and Boussinesqmodel for numerical simulations of rated static load contact, the study showed that under dry friction and grease lubrication, PTFE/ardex pad stabilizes the surface friction coefficient and effectively reduces the friction coefficient. Again, the friction coefficient of the aluminum self-lubrication increases with the texture share and the sample with 15% share shows the lowest friction coefficient (0.114), under lipid lubrication conditions. It is recommended for future research to conduct a wobble (transient dynamics) and thermodynamic analysis for the model, and attempt to optimize the friction resistance of self-lubricating joint bearing by adjusting the deposition process parameters like current value, temperature and element contact.

“…Garcia et al [ 147 ] in modeling analyzed also hydrodynamic lubrication and contact between asperities. They found that surface texturing of the liner led to a reduction in the asperity contact force of 20%, a total friction force of 5%, and an increase in minimum oil film thickness of 4%, so the power loss can be reduced.…”

The effect of cylinder liners on engine performance is substantial. Typically, the cylinder surfaces were plateau honed. However, recently additional dimples or grooves were created on them. This work discusses the tribological impacts of textured cylinder liner surfaces based on a review of the literature. The results of the experimental research obtained using test rigs and fired engines were critically reviewed. In addition, the results of the modeling are shown. Circular oil pockets and grooves perpendicular to the sliding direction of piston rings of small depths were typically used. Surface texturing of the cylinder liners governs lubrication between the cylinder liner and the piston ring by an increase in oil film thickness near the reversal points leading to reductions in friction force and wear and in the fired engine to a decrease in fuel consumption and to an increase in power or torque. The correct texturing pattern ensures a decrease in the oil consumption, blow-by, and emissions of the internal combustion engine compared to plateau-honed surfaces. Considerations of future challenges are also addressed. The volume of lubricant reservoir in surface topography, called oil capacity, should be a substantial parameter characterizing textured surfaces.

“…They observed crossed-hatch angle as a crucial parameter and significant reduction in friction coefficient has been observed. Garcia et al 23 showed and experimentally verified that by surface texturing 25% and 5% reduction in asperity contact force and total friction force can be achieved. Xiuyi et al 24 proposed an improved contact model for analysis of tribological performance of PRCLC from the perspective of Stribeck curve.…”

The tribological performance of piston ring-cylinder liner conjunction (PRCLC) notably depends on the surface finish of cylinder liner. This study investigates the mixed lubrication condition near dead centres considering non-Gaussian roughness and cavitation. The non-Gaussian flow factors are incorporated in the average Reynold's equation to include the effect of non-Gaussian roughness. Whereas, the Weibull probability distribution function is employed to model the asymmetry in asperity heights. It is found that surfaces with more negative skewness exhibit lower engine total frictional force in the vicinity of the dead centres. No substantial effect of the skewness and surface roughness is observed in the mid-stroke of the piston. It is shown that PRCLC operates in mixed-EHL regime near the dead centres. The lambda ratio is found to increase with an increase in skewness of the rough surface.
