Enhancement of Cu Nanoparticles Dispersion in Nanolubricants by Magnetron Sputtering Deposition and Its Influence on the Tribological Behavior

Abstract

We investigate the chemical, physical and tribological properties of nanolubricants consisting of epoxidized sunflower oil with Cu nanoparticles as additive, the latter produced by magnetron sputtering at distinct current levels in the deposition, to improve the development of nanolubricants by enhancing the nanoparticles dispersion. The nanolubricants are here characterized by Fourier Transform Infrared spectroscopy, zeta potential, UV-vis absorbance spectroscopy, small angle X-ray scattering and scanning electron microscopy. After all, the tribological properties of the bionanolubricants are investigated using a high frequency reciprocating ring equipment, scanning electron microscopy, and energy dispersive spectroscopy. Our results place the nanolubricants produced using the magnetron sputtering technique has excellent nanoparticle dispersion, as well as good tribological performance.

A review of advances in tribology in 2020–2021

“…Oxide and metallic nanoparticles can also be used as effective lubricating additives, such as Ni nanoparticles [71], SiO 2 nanoparticles [72][73][74], CuO nanoparticles [75], oleylamine (OM)-modified CeO 2 nanoparticles [76], SiO 2 @Cu microspheres [77], ZrO 2 nanoparticles [78], carbon quantum dot (CQD) and Ni-CQD particles [79], Cu nanoparticles [80], cubic nickel nanoparticles modified with oleymine [81], some magnetic nanoparticles [82], nano-silver [83] , etc. Nanofluids formed from metal compounds also work well as lubricant additives [84][85][86][87].…”

Investigation of the effects of orthodontic brackets coated by silver hydroxyapatite, copper oxide, and titanium oxide nanoparticles on wire-bracket friction

“…Coated copper nano-additives can significantly improve abrasion resistance as well as reduce the coefficient of friction. [23,25,[27][28][29][30][31] e study results of the effects of copper nanoparticles by Hu et al on friction surfaces showed that reducing friction at low velocities is more than high velocities. [30] In a study by Na et al, friction between the brackets coated with titanium dioxide (TiO2) nanoparticles and wire was measured.…”
