Abstract

The aim of this study was to determine the sliding wear behavior of γ-irradiated linear polyethylene. The polymers used were two linear polyethylenes that were irradiated by g rays at room temperature. Equal total doses of 2, 5, 10 and 20 Mrad were applied. Tribological tests were performed in a Pin On Disc tribometer with normal loads between 2, 5 and 15 N. The results show that the wear rate increases with the applied load in the case of the samples irradiated with the lowest doses, while the wear rate displays a maximum with the applied load in the samples irradiated with the highest dose.
