“…They are diverse in nanostructures, compositions, and physiochemical properties and, thus, have shown promises in various applications. In lubrication science, metallic, ceramic, and carbon-based NPs have been explored as potential additives to reduce friction and wear. − Furthermore, some types of nanomaterials were found to provide synergistic effects when used together. − Ag NPs were reported to be utilized with MoS 2 or graphene to synergize the friction and wear performance. ,, Deposition of Ag NPs enhanced the graphene lubrication by preventing the nanosheet restacking during the rubbing process. Further, the anchored Ag NPs help to exfoliate the graphene nanosheets facilitating the interlamination sliding .…”

The reactivity and functionality of nanoparticles (NPs) are determined by the material- and size-dependent physicochemical properties at nanoscale. While single-type metallic NPs have been extensively studied for many potential applications, combination of multitype NPs and the interactions among them have received less attention. Here, an interesting synergistic effect between silver and palladium NPs is presented for using them together as lubricant additives. Dodecanethiol-modified Ag and Pd NPs were discovered to interact actively in a solution, changing their sizes, shapes, and electronic structures. A mixture of these two NPs was able to form a stable suspension in a lubricating oil and effectively improve tribological performance in the concentration range of 0.1–1 wt %. The Ag–Pd NP blend further reduced the friction and wear by >30% and >80%, respectively, compared with either NP alone at the same total NP concentration. The NPs and worn surfaces were characterized using a set of comprehensive analytical tools and the superior lubricating behavior was attributed to the formation of two types of protective tribofilms on the contact surfaces.

“…Synergistic lubrication effect may improve the tribological performance of nanolubricants by integrating two or more mechanisms, and this effect is usually contributed by composite nanoadditives [21,78,84,115,118,121,225]. A synergistic effect is also reported for some other nanoadditives such as metal carbide [90], nitrides [159,160], and oxides [73,96,108,130,146,147,154], and these nanoadditives themselves play multiple roles in combining two or more lubrication effects together for enhanced lubricity.…”

Applying nanomaterials and nanotechnology in lubrication has become increasingly popular and important to further reduce the friction and wear in engineering applications. To achieve green manufacturing and its sustainable development, water-based nanolubricants are emerging as promising alternatives to the traditional oil-containing lubricants that inevitably pose environmental issues when burnt and discharged. This review presents an overview of recent advances in water-based nanolubricants, starting from the preparation of the lubricants using different types of nanoadditives, followed by the techniques to evaluate and enhance their dispersion stability, and the commonly used tribo-testing methods. The lubrication mechanisms and models are discussed with special attention given to the roles of the nanoadditives. Finally, the applications of water-based nanolubricants in metal rolling are summarised, and the outlook for future research directions is proposed.

“…Li et al [104] fabricated GO-3-aminopropyltriethoxysilane (GO-3-APS) film on a bronze substrate resulting in durable lubrication film during water lubrication. The additional results showed that the COF and the wear rate of the composite coating decreased by 43.6% and 79.7% versus blank substrate under pure water lubrication.…”

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.
