Effect Of Surface Temperature On Tribological Behavior Of Polytetrafluoroethylene Composites

Abstract

The tribological behavior of polytetrafluoroethylene is highly affected by fillers used to improve its mechanical characteristics and depends on the ability of the material to maintain its integrity under working conditions. Specifically, in the case under study, the heat generated by friction was modelled as a heat flow coming from a source at the contact surface in static condition. Considering that a heat flow is also supplied to the samples during a differential scanning calorimetry analysis, when the crystallinity of the material is evaluated, a correlation between the thermal characteristics of the material, its structure and tribological behavior is presented.
