“…Song [141] studied the tribological behavior of GO in pure water for the first time and found that the water with GO nanosheets shows better tribological properties than the pure water and the water with oxide multiwall carbon nanotubes (CNTs-COOH). Recently, Kinoshita [142] also reported that adding GO particles into water improves lubrication and provides a very low friction coefficient with virtually no wear. The applications of GO sheets as a water lubricating additive create favorable conditions for the bio-tribological application of GOBMs.…”

Graphene oxide (GO) can be readily modified for particular applications due to the existence of abundant oxygen-containing functional groups. Graphene oxide-based materials (GOBMs), which are biocompatible and hydrophilic, have wide potential applications in biomedical engineering and biotechnology. In this review, the preparation and characterization of GO and its derivatives are discussed at first. Subsequently, the biocompatibility and tribological behavior of GOBMs are reviewed. Finally, the applications of GOBMs as lubricants in bio-tribological systems are discussed in detail.

“…Meanwhile, nanoparticles are candidates of additives because their smallness is advantages for formation of thin films and for entering friction interface. It has been reported that using nanoparticles as additives could improve tribological properties [4][5][6][7]. Joly-Pottuz et al have reported that addition of carbon onions as additives in a poly-alphaolefin (PAO) synthetic base oil gives friction-reduction and anti-wear properties under boundary lubrication.…”

Formation of Lubricious Carbon Films by Added Carbon Nanohorns in Water

Effect of carbon nanohorns (CNHs) as additives on tribological properties of self-mated silicon carbide (SiC) in water was investigated. Friction coefficient could decrease with increasing concentration of CNH in water, and minimum friction coefficient of 0.04 was obtained with water containing 1.00 mass% of CNH in severe contact condition. It was found that CNHs form lubricious carbon films on the rubbed surfaces. Formation of carbon film was controlled actively by introduction of laser-surface texturing to substrate, resulting that standard deviation of friction coefficient decreases more than 50% as compared to that without texturing.

“…Hiralal et al [18] used the DS as the oil additives, and compared the tribology behavior of the lubricating oil with different sizes and shapes of DS particles. Moreover, scholars studied several carbonaceous materials that can influence wear behavior [19][20][21]. Overall, we can conclude that texture can affect tribological performance and DS may cause severe wear.…”

Tribological properties of nano diesel soot (DS) as an additive were investigated. Textures in linear radiating arrays were prepared on the surface of a spring-steel plate by laser radiation. The texture densities were 19.6%, 22.1%, and 44.2%, and the depth was 30 µm. The results indicated that the textured surface was interacted with additive favorably to improve its tribological performance. Friction coefficients and wear rates of textured surfaces with additive in oil were generally much lower compared to the original surface without additive. The higher area density of the textured surface with the additive in oil had the lowest friction coefficient, as low as 0.12, and also the minimum wear rate, as low as 1 × 10 3 µm/N·m in 100 • C, to be achievable. Such results can be attributed to the formation of the tribo-film and the storage function of the micro-dimple.
