Abstract
The proactive design of tribo-chemistry at friction interface is an effective way to improve the quality of transfer film. Herein, silver served as an assistant in tribo-chemistry, along with graphite incorporated into the short carbon fiber (SCF)/ polytetrafluoroethylene (PTFE)/poly ether ether ketone (PEEK) composite. The lowest wear rate of 3.5 × 10-7 mm3/Nm was achieved for the composite at a graphite content of 5 wt% and a silver content of 5 wt% (Gr5Ag5) under dry friction condition, primarily benefiting from the synergistic interaction of silver and graphite. The transfer of silver and graphite to the friction interface endowed the transfer film with lubricity and load-bearing ability. Crucially, the oxides generated by silver enhanced the strength of the transfer film, and the tribo-chemical reaction involving Ag could increase the bonding of the transfer film to the metal.
