Microtribology and Friction‐Induced Material Transfer in WS2 Nanoparticle Additives

摘要: The tribological behavior of platelet and nested colloidal particles tungsten disulfide was studied using the surface forces apparatus, atomic force microscopy, lateral Auger spectroscopy. Shear-induced material transfer from to surfaces shown be a dominant factor in observed for both structures. An ultrathin, ordered layer when were sheared, while WS2 platelets produced rough disordered layer, with substantially inferior lubricating properties.
