摘要：

Sandwich structure of polyetheretherketone (PEEK)-based dissimilar tribomaterials was successfully prepared by vibration welding for investigating the friction and wear properties by releasing particles onto the polymer/steel interface. The tribological properties of the welds were studied on a pin-on-disc tribometer under various loading conditions. The results obtained demonstrate that the nano-sized rigid particles create an obvious synergetic effect with the short carbon fibers (SCFs) and graphite on reducing the friction and wear of PEEK/SCF/graphite composite. The mechanisms on the improving tribological properties were revealed based on the analysis of the polymer worn surfaces and tribofilms. The present study provides a new insight in tailoring polymer-based tribomaterials by using a particle depot concept in engineering of tribological components.
