Abstract
The tribological behavior of surface-capped MoS3 nanoparticles (nano-MoS3) in hydrocarbon oils was studied both alone and in combination with ZDDP. It was found that the nano-MoS3 additive alone demonstrates pro-wear properties and decreases the friction coefficient only at high temperatures. The combination with ZDDP demonstrates synergism in antiwear and antifriction activity even at low ZDDP content. X-ray Absorption Near Edge Structure (XANES) spectroscopy at the sulfur, molybdenum and phosphorus edges was used to identify the chemical species in tribochemical films. It was established that the nano-MoS3-formed tribofilms are composed of oxidized sulfur and molybdenum species while tribofilms formed by combination with ZDDP are composed of phosphate layers incorporating MoS2-type fragments providing friction reduction.
