Abstract

Polytetrafluoroethylene (PTFE) possesses exceptional lubricating properties; however, its uses are limited due to its high susceptibility to wear. In an effort to overcome this shortcoming, a great deal of focus is placed on creating PTFE composites that exploit the strengths of PTFE and also reduce or eliminate its weaknesses. This investigation explores the use of Au nanoparticle-filled PTFE films to produce low-friction and low-wear surface coatings. PTFE + Au nanoparticle composite films were produced by dip coating stainless steel substrates into a mixture of colloidal PTFE and Au nanoparticles. Tribological tests showed that the composite film has a wear life that is twice that of pure PTFE and possesses an average coefficient of friction that is up to 50 % lower. PTFE suffers delamination as a result of poor adhesion of the film to the substrate and tearing resulting from a dominant adhesive wear mode. PTFE + Au, on the other hand, shows no sign of delamination or adhesive wear. This change in wear mode caused by the addition of Au nanoparticles significantly increases the wear resistance and durability of PTFE.
