Tribological performance of graphite-filled polyimide and PTFE composites in oil-lubricated three-body abrasive conditions

Graphite filled polytetrafluoroethylene (PTFE) and polyimide (PI) composites were tested against tool steel under nominal contact pressure of 6.32 MPa and sliding speed of 1.91 m/s in clean ISO 46 lubricant, and also contaminated lubricant with 4200 ppm of silica sand. Pin-on-disk test results show...
