Tungsten Disulfide (WS2) Powder | Ossila

One of the most distinctive features of tungsten disulfide (WS 2) is its performance as a lubricant, even under harsh conditions (e.g. high temperature and high pressure).Its coefficient of friction (CoF) of 0.03 is nearly unmatched. Depending on the techniques used in its preparation, exfoliated 2D WS 2 layers have three crystal phases: octahedral (1T) and hexagonal (2H and 3R).

Coefficient of Friction | Scientific.Net

The images of scanning electron microscope reveal that particles of tungsten disulfide concentrating on the friction surface is likely responsible to a reduction in the coefficient of friction and increase the wear resistance of PTFE-based polymer composites with complex fillers.
