摘要

The tribological behaviors of novel porous Polyetheretherketone (PEEK) composites under 1-hexyl-3-methylimidazolium tetrafluoroborate ionic liquid lubricated condition were investigated. The effect of sliding velocity and applied load on the sweating tribological properties and the stability of lubricating oil film was also studied. Results indicated that when the sliding velocity was 0.69 m/s and the applied load was 250 N, the friction coefficient and wear rate of the ionic liquid lubricated porous sweating activated carbon fiber/polytetrafluoroethene/PEEK composites showed the minimum values, were 0.0197 and 4.145 × 10~(-15) m~3/Nm, respectively. The friction coefficients fluctuated in a narrow range of 0.0162-0.0215. It was found that the porous sweating PEEK composites under ionic liquid lubricated condition showed good low-friction and antiwear performance, especially under the condition of high sliding velocity and applied load. The formed transfer film due to the tribo-chemical reaction as well as boundary lubricating film is effective in improving the carrying capacity and antiwear properties of the porous sweating PEEK composites.
