Graphite Fluoride as a Solid Lubricant in a Polyimide Binder.

Abstract

Polyimide resin (PI) was shown to be a suitable binder material for the solid lubricant graphite fluoride ((CF1.1)n). Comparisons were made to similar tests using PI-bonded MoS2 films, (CF1.1)n rubbed films, and MoS2 rubbed films. The results showed that, at any one specific temperature between 25 and 400 deg C, the wear life of PI-bonded (CF1.1)n films exceeded those of the other three films by at least a factor of 2 and by as much as a factor of 60. Minimum friction coefficients for the PI-bonded films were 0.08 for (CF1.1)n and 0.04 for MoS2. The rider wear rates for the two PI-bonded films at 25 C were nearly equal.
