N2 - Single-filler polytetrafluoroethylene (PTFE) composites with different filler materials are prepared and their tribological characteristics are evaluated in gaseous hydrogen to investigate the tribological function of each filler material. The results indicated that glass fibre caused severe abrasion on the cast iron sliding counterface and hence increased wear in both the composite and counterface in hydrogen. The friction and wear characteristics of polyphenylene sulphide-filled PTFE in hydrogen are similar to those in ambient air because it formed a PTFE-based transfer film on the counterface regardless of the surrounding atmosphere. On the other hand, carbon fibre-filled PTFE indicates excellent low friction and low wear in hydrogen. In this case, both the composite surface and sliding counterface are covered with carbon-rich tribofilms.
