FORMATION OF PHYSICAL INTERACTIONS IN POLYMER-STEEL FRICTION PAIRS

Journal Title: Tribologia - Year 2016, Vol 267, Issue 3

Abstract

This article presents the results of tribological studies of metal-polymer pairs by taking into account a wide range of the externally applied parameters of friction pairs (pressure, rubbing speed), reaching the limits of polymer flow. Adhesion is the dominant mechanism of the wear of polymer-steel friction pairs; it triggers off the transfer of the polymer onto the metal as a result of local joining between the chains of hydrocarbons and the active centres located on the surface of the steel element. The main reason for this phenomenon is the high oxidation susceptibility of the metal element and, as a result, a tendency for oxide formation on its surface. This is a spontaneous phenomenon that is taking place in a short time, and the degree of over-reaction depends on the duration of exposure, humidity, temperature, the presence of impurities on the surface of the metal element, and many other factors. Therefore, limiting the formation of oxides on the surface of the metal element is a key issue related to enhancing the resistance of a polymer-metal friction pair resistance to adhesive wear.<br/><br/>

THE INFLUENCE OF A CONSTANT STATE OF DEFORMATION ON THE FRICTION COEFFICIENT IN SELECTED THERMOPLASTICS (POLYMER–STEEL PAIR)

The effect of tensile deformation on polymer structures and their mechanical properties is described in various papers. However, the majority of articles are focused on high deformation (a few hundred percentiles) at inc...
