“…This further demonstrated that SA/CeBO 3 acted as an efficient friction and wear reducer in rapeseed oil at relatively low contents. Decrease of anti-wear and friction-reducing abilities of SA/CeBO 3 at high contents should be attributed to the conglomeration of SA/CeBO 3 nanoparticles under frictional heat [31]. Fig.…”

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.

Surface-modified ZnS nanoparticles have been fabricated, and the morphologies and crystalline structures of the powder have been characterised by transmission electron microscopy, X-ray diffraction and Fourier transformation infrared spectrum. The tribological properties of the surface-modified ZnS (SM-ZnS) nanoparticles as an additive in PEG400 were evaluated with a four-ball tester. It was found that the as-prepared SM-ZnS nanoparticles had a very narrow size distribution, with the average diameter about 5-10 nm. The SM-ZnS nanoparticles as the additive led to an obvious improvement in the anti-wear and frictionreduction properties of the synthetic PEG400. Analysis indicated that a boundary film was formed during the friction process.
