“…These nanoadditives contribute to enhancing friction-reduction, anti-wear and load-carrying capacities of base water to a large extent, which shows great potential to be applied in hot steel rolling. To name a few, He et al [17] added MoS 2 -Al 2 O 3 nanocomposite into water-based fluid for hot rolling in a 2-high rolling mill. They found that the rolling force and oxide scale thickness of rolled strips obtained using base-fluid lubricating condition were, respectively, reduced by 26.9% and 54.2% after 5-pass rolling.…”

Eco-friendly and low-cost water-based nanolubricants containing rutile TiO2 nanoparticles (NPs) were developed for accelerating their applications in industrial-scale hot steel rolling. The lubrication performance of developed nanolubricants was evaluated in a 2-high Hille 100 experimental rolling mill at a rolling temperature of 850 °C in comparison to that of pure water. The results indicate that the use of nanolubricant enables one to decrease the rolling force, reduce the surface roughness and the oxide scale thickness, and enhance the surface hardness. In particular, the nanolubricant consisting of 4 wt % TiO2, 10 wt % glycerol, 0.2 wt % sodium dodecyl benzene sulfonate (SDBS) and 1 wt % Snailcool exhibits the best lubrication performance by lowering the rolling force, surface roughness and oxide scale thickness by up to 8.1%, 53.7% and 50%, respectively. The surface hardness is increased by 4.4%. The corresponding lubrication mechanisms are attributed to its superior wettability and thermal conductivity associated with the synergistic effect of rolling, mending and laminae forming that are contributed by TiO2 NPs.

“…From Figure 7A, when lubricated by base fluid, many defects such as black spots, pits, and scratches appeared on the rolled strip surface. It can be seen that the dark areas in 2D optical micrographs were lower (purple or blue in 3D surface topography) or higher (yellow or red in 3D surface topography) than the strip surface, which indicated the presence of adhesive wear 35 . The abrasive particles generated on the metal surface were transferred to other parts of the strip or the rolling mill, resulting in poor surface quality, which was also the reason for the zigzag and prominent roughness curve.…”

Triethanolamine functionalized reduced graphene oxide (rGO‐TEA(s)) nanocomposites have been synthesized by the hydrothermal method. The physical and chemical properties of rGO‐TEA(s) with different degrees of functionalization were characterized by transmission electron microscopy, X‐ray powder diffraction, Raman spectroscopy, and X‐ray photon spectroscopy. The cold rolling lubrication of the rGO‐TEA(s) prepared as nano‐lubricant additives were investigated using a two‐high rolling mill. The microscopic topographies of rolled strips were measured and evaluated by several physical characterizations. The results showed that the increase of functionalization time was favored to the reaction of triethanolamine and C–O–C groups on the GO surface, whereas the defects and disorder in graphene structure were repaired according to the intensity ratio of the D band to G band from 1.154 to 1.130. The cold rolling experiment results demonstrated that rGO‐TEA(s) exhibited excellent lubrication properties, especially the rolled surface lubricated by rGO‐TEA‐10h presented few defects and minimum roughness value. The admirable lubrication performance of rGO‐TEA‐10h was attributed to the formation of absorption film and consecutive carbonaceous protective film.

“…This method evaluates the particle diffusion moving in Brownian motion and uses the Stokes-Einstein ratio to convert them into particle size ranging between 0.3 nm to 10 µm [181]. Numerous researchers use the DLS method in order to determine the diameter of NPs, although this method is also promising for estimating the size distribution of water-based nanoadditives such as graphene [132,141], ceria [53], and copper [65,117,118,182]. The more stable dispersion of NPs in base lubricant, the greater the impact is on the scattered light intensity, and vice versa.…”

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.
