The Preparation and Tribological Properties of Graphite Fluoride

Solid phase method was adopted to prepare the graphite fluoride solid lubricant. The friction and wear properties of graphite fluoride were tested with MMW-1 vertical universal friction and wear testing machine. The phase of graphite fluoride was analyzed with infrared spectrometer. The morphology of friction surface was analyzed with the scanning electron microscope. The results show that graphite fluoride has an excellent antifriction wear-resisting property, to compare with molybdenum sulfide, the anti-friction property increased by 35%, wear resistance increased by 49%. The main wear mechanism of the test specimens are fatigue wear and adhesive wear. The solid lubrication film for graphite fluoride was formed in the friction surface.
