“…It should be noted that TiO 2 NPs modified by tetra(2-ethylhexyl)-thiuramdisulfide and di(2ethylhexyl)-thiophonedisulfide can be completely welldispersed in the base oil, with no significantly negative effect on anti-friction properties [121,122]. It is important that functionalized TiO 2 NPs exhibit better anti-wear and friction-reducing properties in base oil compared to non-coated TiO 2 NPs.…”

This review focuses on the effect of metal-containing nanomaterials on tribological performance in oil lubrication. The basic data on nanolubricants based on nanoparticles of metals, metal oxides, metal sulfides, nanocomposities, and rare-earth compounds are generalized. The influence of nanoparticle size, morphology, surface functionalization, and concentration on friction and wear is analyzed. The lubrication mechanisms of nanolubricants are discussed. The problems and prospects for the development of metal-containing nanomaterials as lubricant additives are considered. The bibliography includes articles published during the last five years.

“…This can be ascribed to a presence of Fe 2p on the surface of TiO 2 . The shift of the binding energy resulted from the weak signal because the atomic sensitivity factors of Ti 2p are much weaker than that of other elements [32], and the peaks cannot be attributed to any other elements [29,32,39]. It can be seen that the binding energies of Ti2p locating 464.6 (Ti2p1/2) and 458.8 (Ti2p3/2) eV correspond to Ti2O3 and Fe2O3, respectively, which suggests that oleo-phobic TiO2 was degraded to Ti2O3 and reacted with metal surface.…”

“…The binding energy of iron (Fe2p) locates at 707.1 and 711.2 eV, respectively, corresponded to Fe 3+ (oxide), i.e. to Fe2O3 [30,32,[40][41][42]44]. Fe2p spectra showed a presence of Fe 2+ and Fe 3+ .…”

“…The main drawback of this method is that the sedimentation is unavoidable after a long-time storage and the negative effect of same dispersants on tribological properties [28][29][30][31]. The second method is the usage of surfactant [31][32][33].…”

Abstract:To improve the oil-solubility of nanoparticles, a new technology was used to prepare a kind of lubricant containing titanium dioxide (TiO 2 ) nanoparticles. The microstructures of the prepared nanoparticles were characterized via transmission electron microscope (TEM) and infrared spectroscopy (IR). Tribological properties of TiO 2 nanoparticles used as an additive in base oil were evaluated using four-ball tribometer and ball-on-disk tribometer. In addition, the worn surface of the steel ball was investigated via polarized microscopy (PM) and X-ray photoelectron spectroscopy (XPS). The TiO 2 nanoparticles can be completely well-dispersed in the base oil under a new process (NP), which has no significantly negative effect on the anti-oxidation property. The results of the tribological tests show that TiO 2 nanoparticles under the NP show a better anti-wear property and friction-reducing property in base oil compared to TiO 2 nanoparticles under the tradition process (TP). The main aim of this paper lies in solving with the oil-solubility problem through the combination effect of surface modification and special blend process of lubricating oil. This method was first used to prepare lubricant containing TiO 2 nanoparticles and then used as additives in engine oil, gear oil, and other industrial lubricants. At the same time, tribological properties of TiO 2 nanoparticles in base oil as a lubricating additive were also studied.
