With the rapid development of modern industry, traditional lubricants often require a variety additives to be used in conjunction with each other, which not only increases cost but also causes waste resources. Therefore, lubricant additive both dyeing function and an antiwear friction reduction performance can more effectively meet industrial needs. Cerium sulfide (Ce2S3), its excellent photostability, weather resistance, thermal stability, nontoxicity, shows great potential as environmentally friendly pigment. However, methods for synthesizing Ce2S3 are typically hindered by high-temperature requirements toxicity issues, limits broad application lubricants. To overcome these limitations, this study employed liquid-phase method under mild conditions synthesize oleylamine-modified, wrinkle-free nanosheets (OA-Ce2S3 NSs). The friction-reducing properties OA-Ce2S3 NSs poly alpha-olefin-6 base oils were evaluated various four-ball tribometer. Experimental results indicate that significantly enhance forming physical adsorption film ultra thick tribochemical reaction (with typical thickness 350 nm maximum up 700 nm) on surface. Furthermore, elucidates lubrication mechanism proposes their sliding surfaces. This research highlights provides future directions optimizing synthesis multifunctional applications, offering new insights into field science.

In response to the mounting concern over environmental pollution and depletion of petroleum reserves, biolubricants have emerged as a promising alternative mineral oil-based lubricants. Thus, aim this research is tribological characterization green castor soybean nanolubricants containing functionalized CaCO3 nanoparticles. Friction improvements were reached with maximum friction decreases 14 % 18 compared oils. Concerning wear, optimal concentration for was intermediate 0.15 wt% width wear reductions 27 24 oils, respectively. Tribological mechanisms tribofilm formation, repairing rolling-bearing identified. rolling-sliding tests, use nanoparticles crucial at low speeds outstanding reductions.

Different carbon-based nanomaterials (fullerenes, graphene, SWCNTs, and SWCNT-COOH) were tested as additives in a base mineral oil, SN150; rapeseed oil (RSO); 50/50 by volume blend of the two using an HFRR (high-frequency reciprocating rig) tester for coefficient friction (COF) wear scar diameter (WSD) determinations four-ball welding point determinations. The concentrations considered tests 0.1, 0.5, 1, 2 wt.%, while concentration was 0.5 wt.%. results showed that addition different nanoparticles made it so occurred at much lower pressures compared to pure oils. This is due hardness nanoparticles, which increases local temperature pressure contact points between them surfaces, causing occur sooner. possible synergistic effect fullerenes SWCNT-COOH blend, may be attributed interactions molecular level molecules blend.
