“…Khandeker et at [54] reported 150 % increase in thermal conductivity with the addition of Cu nanoparticles into ethylene glycol. Bakalova et al [60] concluded that the addition of particles into conventional fluids enabled to increase the penetrability of fluids into the friction surface, thus resulting in the elastohydrodynamic effect of lubrication along with the reduction of friction coefficient, good stabilization and prevention of bacteria growth [61]. The better performance of nanofluids in terms of cutting force and surface roughness (Fig.…”

“…Additionally, it is shown that nano-cutting fluids have superior cooling properties due to its good heat extraction capabilities [8]. Nano-cutting fluids have shown promising effects on the cutting performance characteristics through different cutting operations such as turning, milling and grinding as has been presented in some previous studies [9][10][11][12][13][14][22][23][24][25][26]. Also, a previous work introduced a detailed model to assess the sustainability aspects (including cutting fluids application) for machining processes [27].…”

Several properties make titanium and its alloy the primary candidate to attain weight and functional advantages because of its promising properties such as high strength to weight ratio, high corrosion resistivity, and high yield stress. Although titanium alloys have superior properties, some inherent characteristics such as high chemical reactivity and low thermal conductivity lead to poor machinability and result in premature tool failure and shortened tool life. In order to overcome the heat dissipation challenge during machining of titanium alloys, nano-cutting fluids are utilized as they offer higher observed thermal conductivity values compared to the base oil. Thus, in the current work, multi-walled-carbon nanotubes (MWCNTs) cutting fluids along with minimum quantity lubrication (MQL) have been employed during machining Ti-6Al-4V. On the other hand, developing a multiobjective optimization model for machining titanium alloys is a promising step in order to minimize machining cost, achieve excellent surface quality, and increase the cutting tool life by selecting the optimal cutting conditions (i.e. cutting speed, feed rate, depth of cut). In this study, response surface methodology (RSM), and genetic algorithm (GA) are employed to model and optimize three main machining responses: tool wear, surface quality, and power consumption. Three main independent processes parameters are considered when machining titanium alloys, namely; cutting speed, feed rate, and percentage of added nano-additives.

“…In addition to the formation of tribofilm, several other lubrication mechanisms of nanoparticles have been proposed by relevant scholars including rolling effect, 2,12 polishing effect, 5,13 self‐repairing effect 14 and interlayer sliding effect 15 . However, these mechanisms are mainly extrapolated from experimental results, which are lack direct evidence and theoretical support.…”

“…However, friction and wear are inevitable during hot rolling process, which will seriously impact the metal surface quality, increase energy consumption and material wastage 1 . In recent years, with the development of nanotechnology, nanofluids containing nanoparticles in the size of 1–100 nm have attracted increasing attention as lubricants for metal‐forming, such as TiO 2 , 2 CuO, 3 MoS 2 , 4 SiO 2 , 5 and graphene oxide 6 . These nanoparticles exhibit superior friction‐reduction and anti‐wear performance in water‐based fluids.…”

The lubrication performance of Cu nanofluid was studied through hot rolling tests and non‐equilibrium molecular dynamics simulation. Results showed that nanofluid with 0.5 wt% Cu nanoparticles possessed the optimal effect in reducing the rolling force, finish rolling thickness and rolled surface roughness. The superior lubrication performance was attributed to the formation of protective tribofilm made of Fe/Cu debris, iron and copper oxides as well as amorphous substances with a thickness of about 24 nm, which avoided the direct contact of steel strip and the roll, thus inhibiting the adhesion wear. Molecular dynamics simulation disclosed that the rolling‐dominated motion pattern of Cu nanoparticles with 74.1% rolling and 25.9% sliding motion contributed to a significant decrease in the friction force. Besides, surface defects including the peaks and valleys were polished and repaired by nanoparticles respectively, thus developing the surface quality of hot rolled products.
