“…Friction and wear between moving components have an important influence on the energy loss of engineering equipment [1][2][3]. Lubrication technology is of great significance to improve the tribological properties and reduce the wear of friction pairs [4,5]. In addition, lubricants have the functions of cleaning wear debris, sealing clearances, dissipating heat, and resisting corrosion or rust [6,7].…”

Molybdenum disulfide quantum dots (MoS2 QDs) are a promising lubricant additive for enhanced engine efficiency. In this study, MoS2 QDs were used as lubricating oil additives for ball-on-disc contact and had adequate dispersity in paroline oil, due to their super small particle size (~3 nm). Tribological results indicate that the friction coefficient of paroline oil with 0.3 wt.% MoS2 QDs reached 0.061, much lower than that of pure paroline oil (0.169), which is due to the formation of a stable tribo-film formed by the MoS2, MoO3, FeS, and FeSO4 composite within the wear track. Synergistic lubrication effects of the tribo-film and ball-bearing effect cooperatively resulted in the lowest friction and wear.

“…Although the damage situations still existed for the samples of 0.05 wt% and 0.1 wt%, the worn degrees were improved than that of containing no additive or high concentration of oil samples. As shown in figure 6, the potential reason is that the appropriate concentrations of copper particles just fill the surface pits, which is beneficial for the improvement of the tribological performance and the excessive copper particles overflow the pits, resulting in the aggravation of surface wear [30,31]. Besides, the viscosity of the composite lubricating oil contained nano-copper particles increased than that of pure paroline oil, this factor can improve the elastohydrodynamic lubrication effect [32].…”

Monodispersed nano-copper particles were prepared, and the optimized method of preparation procedure was established through orthogonal experiments under four different factors. The experimental results show that the particle size of freeze-dried nano-copper particles can be adjusted by rotational speed, freezing rate, types of active agents and freezing mode, and freezing mode is the most important among all of the four factors. Tribological results of the nano-copper particles from the best optimized procedure can be improved 5%-10% than that of pure paroline oil and the lowest coefficient of friction 0.12 can be obtained for the sample of 0.05 wt%. The lubrication mechanism mostly attributed to the appropriate concentration of copper particles filling the surface pits, which is beneficial for the improvement of the tribological performance.
