“…Shaari et al [65] reported that an addition of 0.1 wt.% TiO 2 in palm oil exhibits the lowest friction and wear. Stephen et al [93] investigated the tribological effect of graphene in palm oil with the addition of 25, 50, and 100 ppm and reported that 50 ppm is the optimum concentration. Zhang et al [52] added Sn and Fe in macs base oil with concentrations of 0.1, 0.5, and 1.0 wt%, with the results showing that optimum concentration of both nanoparticles is 1.0 wt%, although Sn was more effective in friction reduction and Fe more effective in wear reduction.…”

In recent years, the tribology field has expanded with the advent of nanolubrication. Nanolubricants are the name given to the dispersion of nanoparticles in a base oil, and has attracted researchers due to its potential application. In addition to being used in the tribology field, nanoparticles are also used for medical, space, and composites purposes. The addition of nanoparticles in base oils is promising because it enhances specific tribological characteristics including wear-resistance and friction, and the most important reason is that the majority of them are environmentally friendly. This paper reviews the tribological effect of various nanoparticles as lubricant additives. Parameters of nanoparticles that affect tribological performance, the technique to enhance stability, and lubrication mechanism that is currently believed to function will be delineated in detail. Moreover, this review facilitates an understanding of the role of various nanoparticles, which helps in developing and designing suitable nanolubricants for various applications.

“…Recent research has suggested that additives like Graphene and MoS2 are good options for lubricant additives to reduce friction and wear (Berman et al, 2014;He et al, 2020;Lin et al, 2011;Meng et al, 2020;Wu et al, 2018). The addition of graphene nanoparticles was reported to boost the tribological properties of vegetable oils and decrease the coefficient of friction and wear scar diameter (Kiu et al, 2017). It has been proved that MoS2 and Graphene nanoparticles, when added in the mixed form, are very effective in reducing friction and wear even better than when added individually (Gong et al, 2017;Xu et al, 2015).…”

It is imperative to emphasize the wear-reducing and load-sustaining abilities of the lubricating oils, as they are an essential part of their operation. In this study, the anti-wear and extreme pressure (EP) performance of Jatropha oil was explored. The investigation was executed on a 4-ball tester machine according to ASTM-D-4172 and D-2783 standards. Nano-sized Molybdenum disulfide and graphene were added to the base oil, whose addition reduced the wear on the test balls but failed to improve the EP properties. However, the addition of Garlic oil elevated the EP properties of the base oil. The Last Non-seizure load and weld point of the jatropha oil was elevated by up to 3 levels, while the Load Wear index was increased by 91.88%. The Flash Temperature Parameter of jatropha oil was increased by 658% and 250% at 100kgf and 126kgf load, respectively, after the addition of 5% garlic oil. Further, the wear scars were examined under an optical microscope and FESEM, which proved that the addition of nano-additives reduced the wear of the balls during anti-wear tests at lower loads, and garlic oil reduced the wear in EP conditions and produced smoother surfaces. These improvements were attributed to the formation of tribo-films on the surfaces as characterized by the EDS analysis. It was concluded that Garlic oil could be a substantial EP additive to vegetable oils (especially jatropha oil) to lift their load-carrying capacity without hampering their environmentally friendly nature.

“…The rubbing action speeds up the flow between the block and the disc, separating the portions of the wake that are most disrupted by the collision. Interaction with the end wall block causes horseshoe vortices, and the pin causes unstable vertical shedding (Kiu et al , 2017). These methods help to increase the flow’s turbulence, which in turn improves convective heat transfer.…”

Purpose The purpose of this study is to investigate the use of micro-pits technology to the problem of tribological performance in a sliding motion. Design/methodology/approach Vegetable oil is a sustainable and economically viable alternative to both mineral and synthetic oils, offering significant savings in both the cost of research and manufacturing. To solve the depriving issue and boost lubrication film thickness, the micro-pits on the surface may function as reservoirs that provide the oil to the contact inlet area. In this research, an aluminium block is used as the workpiece material in an evaluation of a through pin-on-disc tribotester. Lubricating oil in the form of super olein (SO) was used in the experiment. Findings The results show that the friction performance during a rubbing process between a hemispherical pin and an aluminium block lubricated with SO using aluminium alloy materials, AA5083, was significantly improved. Originality/value In this study, a material that breaks down called SO, which is derived from the fractionation of palm olein, was used to use a modified aluminium micro-pit sample that will serve as a lubricant reservoir in pin-on-disc tribotester.
