“…Numerous comparisons have been performed to examine the anti-wear features and thermal performances of nano-MoS 2 additive oil-based fluids. The outcomes confirmed that the tribological and thermal aspects of the prepared nanofluids are strikingly enhanced by adding nano-MoS 2 particles to the utilized fluid [30,[33][34][35]. Dinesh et al [36] scrutinized the tribological and thermophysical characteristics of engine oil comprising MWCNT and Zinc…”

In this research, two different diesel oil-based nanofluids were prepared and the influence of temperature and nanoparticle content were examined on viscosity, tribological, and physicochemical features of diesel oil. The kinematic viscosity of samples was experimentally evaluated based on standard ASTM D445. The greatest viscosity increment was diagnosed at 0.7 wt.% and 100°C for both of the prepared nanofluids. The anti-friction behavior of the nanofluids was studied utilizing a pin-on-disc tribometer. The acquired outcomes revealed that ZnO and MoS 2 nanoparticles (NPs) could promote the tribological characteristics of pure diesel oil. By analyzing the friction coefficient values and line roughness of the wear surface (Ra), an optimal concentration of ZnO and MoS 2 nanoparticles (NPs) were found to be around 0.4 wt.% and 0.7 wt.%, respectively. The friction factor and pumping power were also measured at diverse content of nanoparticles and flow rates showing that the pumping power was enhanced by the incorporation of nanoparticles.

“…The average force reduction when using GraO_0.1% and GraO_0.5% were 20 N to 40 N. The reduction of main cutting force could be ascribed to the lubrication effect of nanofluids at the tool/workpiece interface. Based on the lubrication mechanism of Gajrani et al (Gajrani et al, 2019), the nanofluids could reach the friction interface due to the vibration of the tool and workpiece system.…”

“…For example, Li et al (Li et al, 2014) added MoSe 2 powders into oil-based coolant liquid to make mixed nanofluids in friction tests and found that the new nanofluids showed better friction-and-wear properties because of the formation of a tribofilm at the sliding interface. Gajrani et al (Gajrani et al, 2019) investigated the nanofluids consisting of commercial mineral oil and 0.3 % nanoparticles (MoS 2 and CaF 2 ), and an average increase of 15% in the overall thermo-conductivity of the cutting fluid was achieved. Sridharan and Malkin (Sridharan and Malkin, 2009) compared the performance of nanofluids which consisted of oil and two kinds of nanoparticles, carbon nanotubes (CNT) and MoS 2 respectively, and found CNT nanofluids had better performance on lubrication compared with that of MoS 2 nanofluids.…”

Ti6Al4V is widely used in industry due to its outstanding mechanical properties. However, the severe abrasion and high temperature at tool/chip and tool/workpiece interfaces cause various types of tool wear in machining Ti6Al4V. To ensure high machining efficiency and high quality of machined surface, cooling fluid is often used to reduce the cutting temperature and friction. In this paper, the cooling and lubricating effects of coolant with graphene oxide nanosheet suspension were investigated experimentally and theoretically. Cutting experiments were conducted to compare the performance of

“…This is mainly due to the fact that the water molecules tend to interact with the charged particles. For example, some surfaces such as TiO 2 meet strong wettability [10][11][12] as it is composed of two charged components. Nevertheless, there can be found many surfaces with charged components without strong wettability.…”

How electrostatic and non-electrostatic interactions play a role in water wettability of possible nanostructure surfaces

et al. 2020

The present paper investigated the effects of the electrostatic and non-electrostatic interactions on the water wettability of a surface. Based on this aim, examinations are performed on the molybdenum disulfide (MoS 2) as possible nanostructure surface. The results obtained through calculating the water contact angle on the MoS 2 surface indicate which this surface is a weak hydrophobic substrate. The present simulations illustrate that the electrostatic interactions have little impact on the wettability amount of the MoS 2 substrate. However, the molybdenum disulfide is composed of two charged parts with significant values. In addition, it is observed that the relation between density, van der Waals and electrostatic interactions is different from each other. It have been observed that the van der Waals interactions have direct relationship with water density while there is not anything between the electrostatic interactions and water density peak. The Obtained results via simulation demonstrate that the effectiveness of electrostatic interactions on the wettability depends on the sigma in the Lennard-Jones equation. In the other words, the role of electrostatic and van der Waals interactions on the wettability are not indissociable from each other and this method is sufficient in nanostructure systems.
