Abstract
IN a recent study in this laboratory of the frictional properties of ‘Teflon’ (polytetrafluoroethylene) two experimental results stand out: (1) the coefficient of friction at low sliding speeds is very low (0.05–0.08), as reported in the literature, only if the surfaces have not previously been subjected to high-speed sliding; (2) with rising temperature, there is a marked increase in the friction of ‘Teflon’ on ‘Teflon’ in the vicinity of 20° C, where a phase transition in ‘Teflon’ is known to occur.
