چکیده
Inorganic nanotubes (INTs) and fullerene-like nanoparticles (NPs) of WS2/MoS2 penetrate exfoliate at the contact interface facilitate tribofilm formation. While tribological properties are greatly improved by exfoliated NPs that shed easily, they may be diminished agglomeration in oil. Therefore, surface functionalization is employed to improve dispersion oil-based suspensions. Here, WS2 INTs were functionalized polytetrafluoroethylene (PTFE) a simple cost-effective bath sonication method. WS2-INTs with two concentrations added PTFE characterized scanning transmission electron microscopy, micro-Raman spectroscopy, thermogravimetric analysis. Superior distribution was observed before during friction experiments. Chemical analysis showed significantly greater amount PTFE-coated on rubbed surfaces, accordance wear properties.

متن کاملFriction and wear of PTFE - a review
Polytetrafluoroethylene (PTFE) is an important engineering material. When rubbed or slid against a hard surface, PTFE exhibits a low coefficient of friction but a high rate of wear. These unique properties of the polymer have encouraged many mechanistic and physical examinations of the processes involved in the friction and wear of this polymer. A section of such work carried out over the past ...
