In this paper, we review recent research developments regarding the tribological performances of a series of inorganic nano-additives in lubricating fluids. First, we examine several basic types of inorganic nanomaterials, including metallic nanoparticles, metal oxides, carbon nanomaterials, and “other” nanomaterials. More specifically, the metallic nanoparticles we examine include silver, copper, nickel, molybdenum, and tungsten nanoparticles; the metal oxides include CuO, ZnO, Fe3O4, TiO2, ZrO2, Al2O3, and several double-metal oxides; the carbon nanomaterials include fullerene, carbon quantum dots, carbon nanotubes, graphene, graphene oxides, graphite, and diamond; and the “other” nanomaterials include metal sulfides, rare-earth compounds, layered double hydroxides, clay minerals, hexagonal boron nitride, black phosphorus, and nanocomposites. Second, we summarize the lubrication mechanisms of these nano-additives and identify the factors affecting their tribological performance. Finally, we briefly discuss the challenges faced by inorganic nanoparticles in lubrication applications and discuss future research directions. This review offers new perspectives to improve our understanding of inorganic nano-additives in tribology, as well as several new approaches to expand their practical applications.

“…51 Composites typically exhibit superior performance compared to individual NPs due to the synergetic effect of more than one type of NP. 52,53 According to Kumara et al Ag and Pd NPs modified by Dodecanethiol can interact actively, modifying their sizes, forms and electronic structures. A mixture of these two quasi-spherical ultra-small sizes (2-6 nm) NPs could form a stable suspension and effectively increase tribological efficiency in the 0.1%-1% concentration range in lubricating fluid.…”

The most remarkable difference between electric vehicles (EVs) and conventional ones is the fuel burning dependency of the internal combustion engine, while the emerging EVs operate on electric motors. These alternations create staggering shifts in both lubricants' market demand and performance specifications. Lubricants for electrical powertrain constitutes greases, transmission oils, and lubricants for auxiliary systems and do not rely on engine oils as internal combustion vehicles. The new standards will be more focused on lubricants' electrical properties such as breakage voltage and conductivity, coupled with tribological performance under high rpm, corrosion resistance and thermal management benchmarks. This paper thematically reviews the different studies performed with nanolubricants, and how they match EVs' operational requirements. Conclusions from this study can be considered as guidelines for the potential application of nanolubricants in EVs and possible future research that can be accomplished on the topic.

“…Owing to the synergetic effect of more than one NP type, composites usually exhibit superior performance compared to individual NPs [136][137][138]. Thus, Cu/CeO 2 , Al 2 O 3 /SiO 2 , ZrO 2 /SiO 2 , and (Zn-Ni)/nano Al 2 O 3 composite NPs were used as energy-efficient lubricant additives [139].…”

“…Cu NPs and Ag NPs were used as metal cladding modifiers of nanolamellar MoS 2 [144,145] and WS 2 [137] particles. It was demonstrated that such nanocomposite lubricants changed the COF of the original [128] lubricant and significantly improved its wear resistance.…”

View full text Add to dashboard Cite

This review focuses on the effect of metal-containing nanomaterials on tribological performance in oil lubrication. The basic data on nanolubricants based on nanoparticles of metals, metal oxides, metal sulfides, nanocomposities, and rare-earth compounds are generalized. The influence of nanoparticle size, morphology, surface functionalization, and concentration on friction and wear is analyzed. The lubrication mechanisms of nanolubricants are discussed. The problems and prospects for the development of metal-containing nanomaterials as lubricant additives are considered. The bibliography includes articles published during the last five years.
