“…As has been recently studied, the incorporation of nanoparticles into conventional fluids has shown excellent results in tribological performance; reducing wear and coefficient of friction (COF), as well as improving load carrying capacity [8][9][10][11][12][13][14][15][16]. Hernández-Battez et al [12] studied the friction behavior of NiCrBSi coatings lubricated by CuO nanoparticles suspended in a poly-alpha olefin (PAO6) lubricant with a block-on-ring set-up; results showed a decrease of $ 100% in COF with 2.0 wt% CuO.…”

“…Recently, nanoparticles have been investigated as additives for lubricants in order to improve extreme pressure properties, reducing friction and wear, dissipating heat generation and extending tool life [2][3][4][5][6][12][13][14][15]. For example, Taha-Tijerina et al [12] observed an enhancement in thermal and tribological performance of common lubricants by adding very small filler fraction (o0.10 wt%) of 2D-nanosheets of h-BN and graphene (500 by 500 nm, with 5 and 8 atomic layer thickness, respectively).…”

“…MWFs with nanoparticle additives have been widely investigated for the purpose of reducing the mechanical friction and wear between components obtaining very promising results [5][6][7][8][9][10][11][12][13][14]. For example, the wear scar diameters (WSDs) of a synthetic were selected based on a previous study by our group [33].…”

Featured Application: nanoparticle additives for improving tribological properties of metalworking cutting fluids, enhancing tool life and surface finish in machining processes. Abstract:The study of nanoparticles as additives for metalworking fluids (MWFs) with applications in the metal removal processes, or machining, has received increasing attention due to the possible enhancements on tribological properties. In this study, low-cost and environmentally friendly nanoparticle additives of halloysite clay nanotubes (HNTs) were dispersed in metalworking fluids utilized for milling processes. Concentrations of 0.01, 0.05, 0.10 wt. % were incorporated into a mineral oil (MO) and a semi-synthetic fluid (SF) by ultrasonication. The anti-wear properties of metalworking nanofluids were characterized with a T-05 block-on-ring tribotester at a contact pressure of 0.5 GPa. Surface roughness of worn block materials was obtained with an optical 3D surface measurement system. Results showed that at a concentration of 0.10 wt. % HNTs block mass loss was lowered by 24% for the MO + HNTs nanofluids. For the SF + HNTs, a reduction of 63% and 32% in wear mass loss and coefficient of friction (COF), respectively, were found at the same concentration. The tribological enhancing mechanism for the applied contact pressure was proposed to be due to a reduction of the area of contact and nanoparticle sliding between surfaces with no HNT deposition, evidenced by energy dispersive spectrometry (EDS). Furthermore, surface roughness studies of worn blocks showed smoother surfaces with lower groove density with the addition of nanoparticle additives. The results of this study demonstrate that HNTs can improve the lubricity of metalworking cutting fluids used for machining processes, enhancing tool life and providing better surface finish of products.
