“…The characteristic peak at 710.75 eV–711.2 eV is the oxide of iron produced by the friction sub during the friction process. The characteristic peak at 734.5 eV–724.76 eV is the satellite peak of iron oxide 35 . Surface in the process of friction surface formed in the lubricating film not only contains C, O two elements, but also contains iron.…”

The coal indirect liquefied diesel soot (Coal‐to‐liquids diesel soot, CS) was collected by a self‐made soot trapper. CS was modified with cetyltrimethyl ammonium bromide (CTAB) and named as CS‐CTAB. The tribological properties of CS and CS‐CTAB in 10#white oil(10#WO) were tested on a WTM‐2E controlled atmosphere miniature friction and wear testing machine. The morphology, composition, and tribological mechanism of CS and modified CS‐CTAB were studied by using TEM, XPS, XRD, Raman, and other instruments. The results showed that CS modified by CTAB is wrapped and entangled in long chains. Their main structure components are all amorphous carbon with a small amount of graphite crystallites. The addition of CS‐CTAB (0.8 wt%) significantly reduces both AFC and wear rate, with reductions of 32.9% for AFC, and 65.6% for wear rate compared to no additive. The anti‐friction and anti‐wear effect of CS is greatly improved after being modified by CTAB. Mechanism analysis shows that CS as a lubricant additive, acts as a micro‐bearing in the friction process and falls off under the action of shear force to generate an independent graphite sheet, thus forming a graphite protective film on the surface of 304 stainless steel plate. However, CS has the defects of low graphitization degree, large particle size, and easy agglomeration. During friction, uneven adsorption of CS on the surface can worsen wear. However, CTAB modification can improve dispersion stability in 10#WO and effectively reduce wear on the friction surface.

“…It is also pointed out that modified graphene/MoS 2 nanocomposites have good prospects in the field of tribology. Hu et al [109] prepared rice husk charcoal/MoS 2 (RHC/MoS 2 ) nanoparticles by the precipitation method and modified the products with surface modifiers. The tribological properties of the nanoparticles in polyethylene glycol (PEG) before and after modification were tested by a ball-and-disc friction and wear tester.…”

Improving the lubricating properties of base oils through additives is a crucial objective of tribological research, as it helps to reduce friction and wear of materials. Molybdenum disulfide (MoS2) is a 2D nanomaterial with excellent tribological properties that is often used as a lubricant additive. Several studies have been conducted on the preparation and utilization of MoS2 and its nanocomposites as lubricant additives. This paper reviews the research progress on MoS2 nanomaterials as lubricant additives. It firstly introduces various synthesis methods of MoS2 nanomaterials while focusing on the preparation of nano-MoS2 as lubricant additives. It then summarizes the dispersion stability of nano-MoS2 in lubricating oils which has been paid extensive attention. Moreover, this paper reviews and discusses the tribological properties of nano-MoS2 and its various composites as lubricant additives. The possible anti-wear and friction reduction mechanisms of nano-MoS2 and its composites are also discussed. Finally, this paper presents the challenges faced by nano-MoS2 additives in the field of lubrication and the prospects for future research in view of previous studies.
