摘要：

This study examines the tribological performance of an advanced high-performance polymer (HPP), namely aromatic thermosetting copolyester (ATSP), and poly-hydroxybenzoic acid polymer or Ekonol & REG; as additives for polytetrafluoroethylene (PTFE), under unlubricated conditions from room temperature to 300 degrees C. Compared to PTFE-Ekonol composites, PTFE-ATSP blends showed 50% reduction in the wear rate at all tested temperatures and higher wear resistance at different sliding speeds, partially attributed to its viscoelastic stability or higher mechanical strength. Also, a fluoride-rich lubricating transfer film was formed on the metallic counter surface when tested against PTFE-ATSP, and this film is temperature-dependent. PTFE-ATSP blends are an attractive solution for oil-less applications in the temperature range of 25-300 degrees C.
