Frictional Fatigue of a Polymer in Friction on Steel

This paper presents friction fatigue and wear-rate curves plotted using experimental data for a steel 45–polymer F4-VM friction unit. We have found low- and high-cycle fatigue regions and high-fatigue-life regions. The parameters which describe and separate these regions turn out to be stable, e.g., irrespective of which wear-rate characteristic is accepted. The paper provides a phenomenological description of wear processes in these typical regions.
