Lubricating characteristics of polyimide bonded graphite fluoride and polyimide thin filmsA friction and wear life study was conducted on the use of a polyimide (PI) varnish as a binder for the solid lubricant, graphite fluoride (CF(1.1))N. Also studied were the lubricating properties of PI thin films with no solid lubricant additives. For comparison, similar experiments on PI-bonded MoS2 and burnished films of MoS2 or (CF(li))N were conducted. The best results were obtained with the PI-bonded (CF(1.1))N films. The polyimide thin films (with no solid lubricant additives) did not lubricate well at 25 C; however, when heated to 100 C, low friction and long wear lives were obtained.
