Abstract:

Graphite Fluoride CFxn, from several sources, has been analyzed and evaluated for its friction, wear, and lubrication behavior. Pressed pellets, burnished films, and bonded films of CFxn has been compared to similar specimens of MoS2 in several test devices at room temperature conditions. Although the various CFxn materials have been shown to vary in chemical composition, color, impurity levels, and thermal stability, no significant difference in lubrication performance has been observed between these materials in the lubricant test devices. In general, CFxn has been found to be inferior to MoS2 in its lubrication behavior in the more severe test environments. Therefore, CFxn is not considered to be suitable for use as a solid lubricant in Air Force aircraft and weapon systems having heavy load lubrication requirements.
