In this study, we evaluated the wear of different polymeric materials. The temperatures were also monitored near the articulating surfaces. Six pin-on-disc specimens made out from industrial grade Polyetheretherketone (PEEK), medical grade PEEK, Polyacetal, Ultra High Molecular Weight Polyethylene, Polyetherimide, and Polyphenylene Sulfide. The specimens were tested under ± 8° axial rotation and constant compressive load ranging from 50N–444N. The results of study show an increase in the wear and temperature with increased load. The PEEK-on-UHMWPE material combination outperformed all other tested material combinations in terms of volumetric wear.
