“…The nanoparticles deployed in the rolling application studies were less than 100 nm in size [25]. TiO 2 [26,27], GO [28,29], MoS 2 [30], Al 2 O 3 [31], hBN [32], ZnS [33], MNCS [34], CuO [35], CNT [36,37], SiO 2 [38], and many other nanoparticles have been examined. The incorporation of nano-additives in water and oil emulsions alleviated tribological obstacles [39,40].…”

The purpose of the present article is to dispense an extensive review of research works performed to observe the impacts of nanoparticles tribologically and rationalise the use of nanoparticles in metal rolling lubrication. The results of past experimental research were analysed based on tribological behaviour, lubricant characteristics, and rolling quality. Improvements in tribological behaviour, rolled surface characteristics and mechanical strength were illustrated in the present work. A specific concentration of nanoparticles in the base lubricant was discovered which provided beneficial outcomes. The oxide scale formed as an inevitable byproduct is suppressed by the nano-application. The nanoparticles served better in the rolling process in terms of temperature control due to the enhanced thermal conductivity of the base lubricant. The article advocates for the adoption of nanolubrication in replacement of traditional lubricating fluids in the rolling process. The article lastly presents future challenges and the potential of nanolubricants in engineering applications.

“…Hence, oil producers are looking for modern formulas that can meet the necessary technical requirements [12,15]. In the production stage, each engine oil is enriched with additives that improve the operational properties of the base oil [22]. These additives can be divided into three groups, functionally.…”

Paper chromatography is a method that allows rapid assessment of the condition and identification of fuel, water and soot contaminants in engine oil. The paper contains an analysis of the suitability of rapid paper chromatography for assessing the operating quality of engine oil. It takes into account the comparison of physicochemical parameters by classical methods with the quality of commercial paper chromatography. The presented research allowed verifying the suitability of paper chromatography for laboratory evaluation of engine oil quality. It was found that a more extensive analysis of the oil condition is possible provided that the chromatographic separation time of oil dispensed onto filter paper is increased from 1 minute to 40 minutes. Linear relationships were observed between the surface area of the stain core after 40-minute separation and selected viscosity parameters (e.g. kinematic viscosity measured at 40° C). Based on rapid paper chromatography, it was found that reasonable decisions can be made about the quality of engine oil, and thus about replacement or further use of the oil.

“…To motivate these abovementioned materials' use and realization of superlubricity, carbon nanomaterials, such as carbon nanotubes (CNTs) and graphene have been considered potential candidates for the perfect optimization of previous tribosystems, due to their structural diversity, excellent physicochemical characteristics, low costs [24][25][26][27], etc. As a consequence, the typical carbon nanomaterials, including fullerenes, CNTs, graphene, and nanodiamonds (NDs) are regarded as the subsections.…”

“…With respect to the graphene, it is a flat sheet one-atom thick, where the carbon atoms are bonded through sp 2 packed tightly into a honeycomb lattice. Both CNTs and graphene have been increasingly regarded as nanoadditives to improve the mechanical and tribological performances of materials, thus motivating great developments in bioengineering, electronics, and aerospace [3,24,[34][35][36]. Moreover, 3D-NDs are of both sp 2 and sp 3 carbon atoms and exhibit the confirmed reconstruction of sp 2 being the key to keep stabilization.…”

In recent years, carbon nanomaterials such as fullerenes, carbon nanotubes, graphene, and nanodiamonds have been regarded as versatile triboproducts such as copper coins for various engineering/commerce-scaled applications. Their large-scale usages as ideal reinforcements for the key tribomaterials are motivated by their huge interfacial areas, unique physical/chemical characteristics, as well as multiple scale load-transferring mechanisms. Numerous investigators have kept on studying the possibilities of using carbon nanomaterials as solid lubricants, lubricating additives, or the superlubricated push hand. This review offers a comprehensive discussion of up-to-date survey in carbon nanomaterials for achieving the low friction and high wear resistant in the forms of coatings, bulk materials, lubricants; or even superlubric state in the tribosystems from nanoscale to macroscale. Finally, important conclusions, foreseeable challenges, and future outlooks for carbon nanomaterials are highlighted as the concluding remarks that are needed to impulse nanotechnology maturation and developments of tribological fields such as copper coin protections.
