“…It can be used to reduce the shear stress between the friction pairs and effectively reduce the friction coefficient [21]. In the initial stage of friction, nano BNNs/Cu composite additives are deposited spontaneously on the surface of CLPR friction pairs to form a physical protective film [43,44] to prevent direct contact with CLPR friction pairs. With the extension of reciprocating friction time, the physical protective film gradually breaks, and nano BNNs/Cu composite additives are released and deposited on the wear interface, repairing the friction contact interface, thereby reducing wear and polishing the surface, reducing surface roughness, and preventing further wear.…”

To improve the tribological properties of the cylinder liner-piston ring, a two-dimensional hexagonal boron nitride/copper composite lubricant additive was prepared and characterized in detail. The tribological properties and lubrication mechanism of nano hexagonal boron nitride composites with different concentrations were studied through the reciprocating friction test on the Rtec friction and wear tester. The results show that copper is successfully reduced and attached to the surface of h-BN nanosheets through the self-polymerization of dopamine, and the spherical structure promotes the interlayer slip of the nanosheets during the reciprocating friction process. The appropriate concentration of nano composite additives has excellent anti-friction and anti-wear properties. At 1 Hz and 100 N, the friction coefficient and wear quality of the nano composite additive with a concentration of 2 wt% were reduced by 29.07% and 76%, respectively. The surface Sq value and Sz value of the cylinder liner sample decreased by 68.06% and 74.47%. At the same time, under the condition of high speed and heavy load, the average wear depth of the cylinder liner sample is reduced by 61.3%. The nano composite material additive forms an excellent friction protective film on the wear surface of the cylinder liner, which can better enter the wear surface of the cylinder liner and produce a filling and repairing effect. The research results provide a method for the use of nano hexagonal boron nitride compound additives to inhibit the wear of cylinder liner-piston rings of Marine diesel engines.

“…It is widely recognized that the tribological properties of 2D nanomaterials are closely related to their size and morphology [99][100][101][102]. In recent years, with the continuous development of the synthesis process, researchers have prepared MoS 2 particles with various morphologies, such as nanoflower [103], nanospherical [104], hollow core-shell [105], nanorod [106], and nanowire [107].…”

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.
