“…Based on past studies, fatty acid is considered as one of the most effective surfactants used in nanofluid preparation. Acid ions can neutralize the positive charges on particle surfaces to restrain further agglomeration [Parametthanuwat et al, 2011, Saterlie et al, 2012, Ran et al, 2016.…”

In this research, friction and wear characteristics of oil-based ZnO nanofluid applied on brass disk specimens using a flat-on-flat reciprocating sliding test were studied. Oleic acid was used as surfactant to improve the stability and dispersibility of the ZnO nanofluid. Metallurgical optical microscopy, scanning electron microscopy and energy-dispersive X-ray spectroscopy were utilized to understand the mechanisms. A 2wt% ZnO nanofluid resulted in 61.1% reduction in coefficient of friction. Good wear resistance was achieved using low concentrations of 0.5wt% and 1wt% ZnO nanofluid. A tribo-film mainly composed of carbon was found inside the wear track, which enhanced the wear resistance and lowered the interface shear strength. This tribo-film was produced by oleic acid which was chemically adsorbed to the brass materials.

“…The deposition of ZnO and ZrO2 nanoparticles could be enhanced by increasing the nanoparticle content. Xu et al [Ran et al, 2016] studied the effect of concentration on tribological performance of ZnO nanofluids using a four-ball test configuration with 52100 steel balls. The COF and wear were minimum using 0.5wt% ZnO nanofluid.…”

“…Antiwear and friction reduction capability of conventional liquid lubricants can be enhanced because of the presence of nanoparticles. The size, shape, and concentration of nanoparticles play significant roles for the tribological performance of nanofluids . One of the major obstacles of advanced applications of nanofluids is the stability and dispersibility of nanofluids.…”

“…Most of the previous research studies only focused on the tribological performance of nanofluids on hard metals such as cast iron and steel. 3,5,9,12 Little research was done to investigate antiwear and friction reduction characteristics of nanofluids on soft nonferrous materials such as aluminium and brass. In addition, nanofluid experiments conducted with conformal contact are also very limited.…”

In this research, the tribological behaviour of oil‐based SnO2 nanofluid was evaluated using flat‐on‐flat reciprocating sliding tests on brass. Oleic acid was used as surfactant to improve the stability of SnO2 nanofluid. The morphology of the worn surfaces was observed using optical microscopy, scanning electron microscopy, and energy‐dispersive X‐ray spectroscopy. It was found that oil‐based SnO2 nanofluid reduced the coefficient of friction up to 65.4% and the wear volume loss up to 43.7%. In the analysis of the chemical composition inside the wear track, a tribosintered or embedded patchy film containing tin was observed, which protected the surface against wear and lowered the coefficient of friction. The SnO2 nanoparticles might also roll or slide between 2 mating surfaces to prevent adhesive wear.

Hexagonal boron nitride (hBN) is used as an additive in engineering applications such as polymers, ceramics, and coatings because of its anti‐wear and lubrication performance. It has a high potential as a biomaterial, but it has not been evaluated to facilitate joint motion with its lubricating properties until now. In this study, the hypothesis that boron nitride nanoparticles (BNPs) and nanosheets (BNNSs) can facilitate movement in the joint region is evaluated for the first time. Hyaluronic acid‐based hybrid hydrogels are designed to transport BN particles to the target area and pin‐on‐disc tests on cartilage pins paired with glass disks are conducted to determine the validity of the proposed hypothesis. The injectability, mechanical properties, and friction coefficients of hydrogels with the addition of increasing proportions of different hBN morphologies are monitored. As a result, hyaluronic acid has been found to be a suitable carrier for the injectability of boron nitride in biomedical applications. The amount and morphology of boron nitride are observed as two important parameters. A significant decrease in the friction coefficient (18.9%) is observed in the BNNS‐doped hybrid hydrogel compared to the virgin hydrogel. hBN can be considered as a new therapeutic agent with the potential to facilitate joint mobility.
