Abstract:
Friction pairs were composed of carbon fiber reinforced polytetrafluoroethylene (PTFE) composites and 4032 aluminum alloy or anodized 4032 aluminum alloy. Coefficient of friction, scar width and wear morphology were studied by friction and wear test under the conditions of dry friction and oil lubrication. The results show that, under dry friction condition, the serious abrasive wear emerged during the wear process of composites against aluminum alloy, and the scar width is larger. The adhesive wear acted the major role during the wear process of composites against anodized aluminum alloy, and the wear process accompanied by slight abrasive wear. Under oil lubrication condition, with the increase of carbon fiber content, the scar widths of the composite against aluminum alloy or anodized aluminum alloy were decreased, the abrasive wear was not emerged during the wear process.
