摘要
Abstract
Synthetic ester-based lubricants,owing to their excellent lubricating performance and biodegradability,align with the requirements of energy conservation and environmental protection,serving as a critical alternative to mineral oils.To adapt to practical operating conditions,the development of specialized lubricant additives for ester-based oils is essential.This work focused on molybdenum disulfide(MoS2),a typical two-dimensional nanomaterial with remarkable lubrication properties.Through a novel strategy combining tannic acid-iron ion(TA-Fe3+)complexation followed by annealing,an oleylamine-modified carbon-coated MoS2 composite(MoS2@C)was fabricated.The carbon coating served as a protective barrier to prevent the inherent oxidation-induced degradation of MoS2,while the long-chain alkyl groups of oleylamine(OAm)were grafted onto the MoS2@C surface via chemisorption or coordination bonding.The resultant OAm-MoS2@C additive demonstrated stable dispersion in the ester-based oil tri methylolpropane trioleate(TMPTO)over 30 days.The material's structure was characterized using multiple characterization techniques.Notably,with the addition of 0.3％OAm-MoS2@C-300,the average friction coefficient and average wear scar diameter were reduced by 33.0％and 14.4％,respectively,compared to the base oil under a load of 392N.Furthermore,the maximum non-seizure load(PB)and sintering load(PD)were enhanced by 94.9％and 25％,respectively.Finally,the tribological surface was characterized using X-ray photoelectron spectroscopy(XPS)and Raman spectroscopy,revealing a lubrication mechanism characterized by optimized film formation and synergistic lubrication effects.This approach showed promise for applications in cutting fluids,where it could effectively reduce friction and wear.关键词
