Abstract : Graphite fluoride, a proposed solid lubricant material, performed differently on two types of machines. An examination of the wear processes in both machines was undertaken to reconcile the difference. A burnished film of graphite fluoride was used to lubricate the sphere-on-plane (pin-on-disc) and multiple-flat-on-curve (Falex) test configurations. Compressive stress and sphere wear volume were determined as a function of time from the wear scar area on the sphere, measured at various times. Friction coefficients were also determined for the sphere-on-plane test. The initial and final (static) compressive stress values for the multiple-flat-on-curve test configuration were determined. Differences in wear scar areas on the two faces of the vee block were observed. (Author Modified Abstract)
