Abstract

Abstract: In the quest to develop high-performance lubrication additives, a novel nanocomposite comprising biodiesel soot modified by silver (Ag/BDS) was synthesized. The tribological behavior of Ag/BDS nanocomposite as an additive for liquid paraffin (LP) were systematically investigated using response surface methodology. To elucidate the friction and wear mechanisms associated with the Ag/BDS nanocomposite, various analytical techniques were employed, including scanning electron microscopy with energy-dispersive spectroscopy (SEM/EDS), Raman spectroscopy, and molecular dynamics simulations. The results show that the concentration of Ag/BDS has a significant impact on the tribological properties of LP under different applied loads and sliding speeds. Notably, LP containing 0.25% Ag/BDS shows the most favorable tribological performance and in comparison, to pure LP, the average friction coefficient and average wear volume have been reduced by 42.7% and 21.2%, respectively. The mechanisms underlying the reduction in friction and anti-wear mechanism of Ag/BDS have been attributed to the excellent synergies of Ag and BDS. Specifically, the Ag particles facilitate the incorporation of BDS particles in the formation of uniform boundary lubrication films.
