This paper presents the facile synthesis of two different morphologies of WS2 nanomaterials—WS2 hexagonal nanoplates and nanoflowers—by a sulfurization reaction. The phases and morphology of the samples were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The tribological performance of the two kinds of WS2 nanomaterials as additives in paraffin oil were measured using a UMT (Universal Mechanical Tester)-2 tribotester. The results demonstrated that the friction and wear performance of paraffin oil can be greatly improved with the addition of WS2 nanomaterials, and that the morphology and content of WS2 nanomaterials have a significant effect on the tribological properties of paraffin oil. The tribological performance of lubricating oil was best when the concentration of the WS2 nanomaterial additive was 0.5 wt %. Moreover, the paraffin oil with added WS2 nanoflowers exhibited better tribological properties than paraffin oil with added WS2 hexagonal nanoplates. The superior tribological properties of WS2 nanoflowers can be attributed to their special morphology, which contributes to the formation of a uniform tribo-film during the sliding process.

“…Besides, the adsorption of GO on the contact surfaces will bring out the oil phase and reduce friction jointly. The main theories reported to explain the enhancement of GO-based materials include the protecting and self-repairing mechanism [29], and interlayer lubrication mechanism [30,31]. The GO has the similar mechanical properties as graphene with highest intrinsic strength (130 GPa) and outstanding thermal conductivity (5000 W•m -1 •K -1 ) [32].…”

Water is as an economic, eco-friendly, and efficient lubricant that has gained widespread attention for manufacturing. Using graphene oxide (GO)-based materials can improve the lubricant efficacy of water lubrication due to their outstanding mechanical properties, water dispersibility, and broad application scenarios. In this review, we offer a brief introduction about the background of water lubrication and GO. Subsequently, the synthesis, structure, and lubrication theory of GO are analyzed. Particular attention is focused on the relationship between pH, concentration, and lubrication efficacy when discussing the tribology behaviors of pristine GO. By compounding or reacting GO with various modifiers, amounts of GO-composites are synthesized and applied as lubricant additives or into frictional pairs for different usage scenarios. These various strategies of GO-composite generate interesting effects on the tribology behaviors. Several application cases of GO-based materials are described in water lubrication, including metal processing and bio-lubrication. The advantages and drawbacks of GO-composites are then discussed. The development of GO-based materials for water lubrication is described including some challenges.

“…To optimize the lubricating effect of water, researchers have designed a number of layered nanomaterials, such as MoS 2 , WS 2 , , double hydroxide nanoplatelets, and hexagonal boron nitride (h-BN), especially the new emerging graphene − and its derivatives, including graphene oxide (GO), − functionalized graphene oxide, , and fluorinated graphene (FG), − as excellent lubricant additives. It is suggested that the layered structure with weak van der Waals force may account for the remarkable tribology performance when sliding under water environment.…”

Improving the tribological properties of water by adding nanomaterials as water-based lubricant additive has garnered increasing interest for the great potential in range of water-based applications. However, combining ideally two-dimensional layered nanomaterials and zero-dimensional nanoparticles to create synergistic enhancement of lubricating performance under water is still challenging. In this paper, a novel nanomaterial named aminated silica modified graphene oxide (SAG), which combines the layered nanomaterial graphene oxide (GO) and the nanoparticles hydrophilic nanosilica (SiO2) by 3-aminopropyltriethoxysilane (APTES), has been synthesized. The tribological properties of the SAG nanomaterial as additives in deionized water (DI water) are evaluated on a CSM tribometer under high contact pressure. Using the SAG nanomaterial in DI water, besides the very low friction coefficient it produces, dramatically reduces the wear rate of the wear track and especially the ball. More importantly, the SAG nanomaterial outperforms the individual GO and nanosilica in improving wear resistance. The SAG can also prevent the diamond like carbon (DLC) films deposited on the steel substrates from tearing. It is suggested that the excellent mechanical property of GO nanosheets and the microscopic ball-bearings effect of silica nanoparticles, on which is the SAG nanomaterial based, account for the lubricating and antiwear action. As water-based lubricant additives, this novel nanomaterial showing excellent tribological properties is believed to be a potential candidate for water-based lubrication.
