“…Furthermore, Nine et al [26] achieved a significant improvement in thermal conductivity by mixing MWCNT nanoparticles with alumina nanofluids, whereas Ahammed et al [27] recorded an increase of 88.62% in convective heat transfer coefficient and a reduction of 4.7 °C in temperature using alumina-graphene hybrid nanofluids. Zhang et al [28] used MoS 2 -CNT hybrid nanofluids in grinding and yielded lower G ratio and surface roughness compared to MoS 2 and CNT nanofluids. Moreover, studies on the hybridization of different types of nanoparticles showed an enhancement in thermophysical [29] and tribological [30] properties of base nanofluids.…”

A hybrid lubricant with improved thermal and tribological properties was developed by blending multiwalled carbon nanotubes (MWCNTs) with alumina-based nanoparticles into cutting fluid at fixed volumetric proportions (10:90). The hybrid cutting fluid was prepared in different volumetric concentrations (0.25, 0.75, and 1.25 vol%), and the tribological properties and contact angles were measured using pin-on-disc tribometry and goniometry, respectively. The study showed a reduction in wear and friction coefficient with increasing nanoparticle concentration. The cutting fluid performance was investigated using minimum quantity lubrication (MQL) in the turning of AISI 304 stainless steel. Regression models were developed for measuring the temperature and tool flank wear in terms of cutting speed, feed, depth of the cut, and nanoparticle concentration using response surface methodology. The developed hybrid nanolubricants significantly reduced the tool flank wear and nodal temperature by 11% and 27.36%, respectively, as compared to alumina-based lubricants.

“…On contrary, other nanoparticles chemistries, such as CNT, are known to enhance the heat conductivity of the nanofluid. The coefficient of thermal conductivity of carbon multi wall nanotubes is 3000 W/ m K in contrast to 138 W/ m K of MoS 2 nanoparticles [25]. Hence, the torque reduction mechanism that leads to lower surface hardening seems to be mainly due to an exfoliation mechanism of the MoS 2 nanotubes and subsequent adhesion of the MoS 2 platelets on top of Zn-coated steel, combined with a tribochemical reaction that leads to the formation of ZnS.…”

“…TMD nanoparticles are known for their superb low frictional, anti-wear and extreme pressure properties and have shown a promising performance in machining processes. However, these investigations have focussed mainly on grinding [7,24,25], while their potential use in form tapping remains unknown. Further, there is a lack of knowledge on the interaction between TMD nanoparticles and zinc-coated parts, despite their enormous industrial relevance in automotive industry.…”

The paper presents the first use of nanolubricants containing MoS 2 nanotubes for form tapping of zinc-coated steel. MoS 2 nanotubes are known for their superb low frictional, anti-wear and extreme pressure properties and have shown a promising performance as nanolubricant additive in many machining and forming applications. However their interfacial interaction with zinc-coated components commonly used in automotive applications and their synergisms and antagonisms with currently used additives in forming oils are two crucial aspects that have not been addressed so far. The assessment of these synergies is of uttermost importance for developing future nanofluid minimum quantity lubrication formulations, since despite their extraordinary performance, MoS 2 nanotubes are not able to fulfil all the roles expected from a forming oil. To this end, this paper aims to investigate the performance of MoS 2-based nanolubricants in combination with representative forming oil additives. The threads are perform using a form tapping unit with customized data acquisition on zinc-coated steel, as a representative part in automotive applications. The performance of the nanolubricants is thoroughly investigated using advanced analytic methods with the aim of revealing the underlying interface interaction mechanisms for the observed torque behaviour and resulting thread morphology and sub-surface hardness. The results show that MoS 2 nanotubes are able to interact and form a tribofilm in Zn coated surfaces that leads to a superb friction performance. In combination with oil additives, MoS 2 based nanolubricants have a particularly positive synergy with extreme pressure additives in terms of friction reduction, sub-surface hardening and thread morphology. On contrary, the lowest synergy is achieved in the presence of dispersants, leading to higher torques during form tapping and higher sub-surface hardness in the formed threads.

“…Zhang et al [69] evaluated MoS2 nanoparticles in three different oils (soybean, palm and rapeseed oil) as base fluid.it showed that the optimal concentration range of MoS2 nanoparticle is 6% which showed excellent lubricating property which have reduce specific grinding energy and lower coefficient of friction. Zhang et al [68] extended the research by investigating surface quality under MQL grinding of Ni-based alloy with MoS2, CNT and Mix (MoS2+CNT). It showed that Mix MQL showed the best surface quality followed by MoS2, and CNT.…”

Abstract. This paper reviews the recent progress and applications of nanoparticles in lubricants as a coolant (cutting fluid) for grinding process. The role of grinding machining in manufacturing and the importance of lubrication fluids during material removal are discussed. In grinding process, coolants are used to improve the surface finish, wheel wear, flush the chips and to reduce the work-piece thermal deformation. The conventional cooling technique, i.e., flood cooling delivers a large amount of fluid and mist which hazardous to the environment and humans. Industries are actively looking for possible ways to reduce the volume of coolants used in metal removing operations due to the economical and ecological impacts. Thus as an alternative, an advanced cooling technique known as Minimum Quantity Lubrication (MQL) has been introduced to the enhance the surface finish, minimize the cost, to reduce the environmental impacts and to reduce the metal cutting fluid consumptions. Nanofluid is a new-fangled class of fluids engineered by dispersing nanometre-size solid particles into base fluids such as water, lubrication oils to further improve the properties of the lubricant or coolant. In addition to advanced cooling technique review, this paper also reviews the application of various nanoparticles and their performance in grinding operations. The performance of nanoparticles related to the cutting forces, surface finish, tool wear, and temperature at the cutting zone are briefly reviewed. The study reveals that the excellent properties of the nanofluid can be beneficial in cooling and lubricating application in the manufacturing process.
