摘要

The tribological behavior of platelet and nested colloidal particles of tungsten disulfide was studied using the surface forces ap- paratus, atomic force microscopy, lateral force microscopy, and Auger spectroscopy. Shear-induced material transfer from the colloidal particles to the surfaces was shown to be a dominant factor in the tribological behavior observed for both structures. An ultrathin, ordered layer was observed when nested particles were sheared, while WS_2 platelets produced a rough and disor- Dered transfer layer, with substantially inferior lubricating properties.
