“…A broad (almost sharp) characteristic peak at 2θ = 11.56 °C, corresponding to the basal plane (002) with about 54% crystallinity, is visible in the graphene’s XRD pattern, as shown in Figure c. , Due to the formation of a few layers of rGO following the reduction process, the broad peak denotes the phase of crystals that are randomly arranged. Additionally, the interlayer spacing- d (fwhm = 5.13) accounted for 0.35 nm in accordance with Bragg’s law, and the average grain size was calculated from Scherrer’s formula to be 1.67 nm, confirming the removal of functional groups containing oxygen during the process of manufacturing . Also the proper and even suspension of the nanoparticles in the grease can be attributed to the fact that there is considerable improvement in the antiwear and antifriction properties of the nanogrease to that of plain grease (Figures and ).…”

Shahriary et al and Zhu et al employed a modified Hummers’ method to obtain nanoparticles and analyzed their properties using techniques such as visible spectroscopy (UV–vis), scanning electron microscopy (SEM), ultraviolet–Fourier transform infrared spectroscopy (FTIR), and X-ray powder diffraction (XRD) . Among the nanoparticles, Cu, Co, and Fe have demonstrated improved tribological properties.…”

Conventional greases have an exceptional place in the field of lubrication. They are unique in the sense of their areas of application and are very difficult to replace with other lubricating substances for the same reason. The advancements in the field of nanoparticles and the results they provide as an additive in greases have great scientific interest as they improve the tribological properties of greases to a great extent. The current work's aim is to synthesize a nanogripe using graphene oxide (GO) nanoparticles to lithium grease (Li grease), which will increase the tribological properties of the plain Li grease. Steps were taken to investigate the impact of variation of load on the frictional and wear characteristics of nanogrease. Synthesis of nanogrease and tribological evaluation were performed with a magnetic stirrer with a hot plate and a four-ball tester. Results indicated that nanogrease exhibits better tribological properties. It is also found that the antiwear and frictional properties of grease are not proportional to the wt % of GO nanoparticles. It is also detected that with the increase in load, the tribological properties of nanogrease increase.

Proper rolling bearing lubricants and lubrication procedures are critical for delivering adequate bearing performance in critical situations. Main roles of Zirconium di oxide (ZrO2) nanoparticles in engine oil as lubricant additive for rolling bearing are reduction of wear and friction, extension of fatigue life, removal of frictional heat, and protection from corrosion. The present work investigates the tribological properties of SAE20W40MGO and ZrO2 nano particles in SAE20W40 MGO oil for 0.4% concentration between steel/steel contact. In order to study wear under variable speed conditions, four-ball wear tests were carried out with chrome-plated steel balls (Grade E-52100), which were designed using 2 levels of factorial design of experiments (DOE). Nano-lubricant deterioration with and without ZrO2 were determined using empirical equations to project wear with reference to speed and ZrO2 concentration. Results presented that anti-wear properties of the SAE oil samples enhanced with ZrO2 irrespective of speed range.
