“…Based on these data, a 1.0 wt % addition of the additive appeared to improve antifriction and wear reduction, mainly because the additive provided a uniform layer of protection to steel balls. By adding nanometer-sized lubricating oil additives to the cylinder liner and piston ring, a uniform continuous oil film was generated that reduced the contact friction between the friction pair as could occur on the engine surfaces in ship diesel engines . MGTC’s oil additives reduce contact friction between friction pair and surface in the process.…”

“…By adding nanometer-sized lubricating oil additives to the cylinder liner and piston ring, a uniform continuous oil film was generated that reduced the contact friction between the friction pair as could occur on the engine surfaces in ship diesel engines. 26 MGTC’s oil additives reduce contact friction between friction pair and surface in the process. It reduces viscous friction caused by interlayer shear of lubricating oil by acting as ball bearings within MGTC composite nanolubricant additives.…”

The unique structure and physical properties of graphene and anatase TiO2 make them suitable for use as additives for engine lubricants. This study describes the use of dielectric barrier discharge plasma-assisted ball milling to synthesize a multilayer graphene-reinforced TiO2 composite nanolubricant additive (MGTC). A variety of physical and chemical tests were performed to characterize the resulting experimental materials, including X-ray diffraction (XRD), Fourier transform infrared (FT-IR), Raman, X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). Four-ball friction and wear testing machines were used to study the tribological properties and extreme pressure anti-wear properties of a base oil containing 0.1, 0.5, 1.0, and 1.5 wt % of the modified TiO2. Raman spectroscopy, XPS, SEM, and energy-dispersive spectrometry (EDS) analyses were used to examine and analyze the microstructure of the friction pairs. As a result of the plasma-assisted ball milling process, expanded graphite was successfully separated into multilayer graphene nanosheets, and spherical TiO2 was successfully bonded to the nanosheets of the multilayer graphene. The 1.0 wt % composite oil was found to provide good friction reduction and wear resistance. It had a film thickness of 27.5 nm, which was 167% thicker than base oil. Due to its excellent dispersion stability, the MGTC nanocomposite exhibited excellent lubrication performance, which was attributed to the formation of carbon protective films, titanium dioxide deposition films, transfer films, and the occurrence of nano ball effects on the surface of friction pairs.

“…Past studies involving nanoparticles validated the reduction in surface roughness. The synergistic effects of polishing, mending, filling, rolling, load carrying, and contact separation effects during the rolling resulted in improved surface characteristics with minimal flaws [44,[56][57][58]68]. When post-processing of the rolled products is considered, the surface morphology of the hot and cold rolling surfaces is a significant parameter.…”

The purpose of the present article is to dispense an extensive review of research works performed to observe the impacts of nanoparticles tribologically and rationalise the use of nanoparticles in metal rolling lubrication. The results of past experimental research were analysed based on tribological behaviour, lubricant characteristics, and rolling quality. Improvements in tribological behaviour, rolled surface characteristics and mechanical strength were illustrated in the present work. A specific concentration of nanoparticles in the base lubricant was discovered which provided beneficial outcomes. The oxide scale formed as an inevitable byproduct is suppressed by the nano-application. The nanoparticles served better in the rolling process in terms of temperature control due to the enhanced thermal conductivity of the base lubricant. The article advocates for the adoption of nanolubrication in replacement of traditional lubricating fluids in the rolling process. The article lastly presents future challenges and the potential of nanolubricants in engineering applications.
