A Model for Abrasive Polymer Wear
The abrasive mechanism of polymer wear is dominant in the startup, or "breakin", stage of polymer/steel sliding systems. This mechanism controls the polymer wear rate until the voids in the hard metal surface are filled, much like the filling observed with a file when used on soft metals. This …

A prediction of polymer wear using polymer mechanical properties and surface characterization parameters
Polymers were slid on rough hard steel surfaces with normal loads which caused full penetration (real and apparent areas equal) and partial penetration (real less than apparent area). Wear data for polyvinylchloride (PVC) and polychlorotrifluoroethylene (PCTFE) was obtained on a pin-on-disk machine …

An investigation of polymer wear due to fatigue using a constant strain wear test
A constant-strain wear test apparatus was built and used to test polyethyleneterephthalate. The results of the constant-strain wear tests were compared to results from a constant-strain fatigue test. The results of the wear test showed that the polymer did not fatigue below the surface where the …

A radio-tracer study of the effect of surface finish on the transfer of polychlorotrifluoroethylene sliding on mild steel
… finish and the number of repeated passes of polymer over mild steel. Qualitative supporting evidence for postulated transfer mechanisms was obtained using scanning electron microscopy. The results showed that bulk transfer of PCTFE to mild steel does occur at room temperature. Initial …
