Novel lubricant additives obtained from biodiesel soot dotted with silver nanoparticles for tribological applications
简介: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 nano-composite 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 nano-composite,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 un-derlying 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 par-ticles in the formation of uniform boundary lubrication films.展开
