Study on the Influence of Li-Grease EP and AW Performance by Exfoliated MoS2 Nanosheet Additive
Tribological behavior of de-agglomerated and exfoliated active molybdenum disulfide (MoS2) nanosheets as additives in lithium based grease was investigated. MoS2 nanosheets were prepared by mechano-chemical process in a planetary ball mill with selective organic
molecules particularly lecithin (a source of phosphorus (exfoliating/stabilizing agent)) along with antiwear additives (ZDDP). Tribological evolutions show significant influence of MoS2 nanosheets on the friction coefficient, WSD (wear scar diameter) and extreme pressure properties
of lithium based grease. The elemental composition analysis of the wear track shows the presence of Mo, S, and P on the surface protective layer, revealing the formation of a tribofilm containing MoS2 nanosheets along with phosphorus based moieties.
