Abstract: | Blending polytetrafluorothylene (PTFE) to PA6 at different compositions was produced in a corotating twin-screw extruder where, PTFE acts as the polymer matrix and PA6 as the dispersed phase. The tribological properties of PTFE composites filled with PA6 under oil lubrication were investigated. The worn surface morphologies of neat PTFE and its composites were examined by scanning electron microscopy (SEM) and the wear mechanisms were discussed. The presence of PA6 particles dispersed in the PTFE continuous phase exhibited superior tribological characteristics to unfilled PTFE. The optimum wear reduction was obtained when the content of PA6 is 30 vol%. |
