Effect of Sliding Speed and Contract Stress on Tribological Properties of Ultra-High-Molecular-Weight Polyethylene.

Abstract

A pin-on-disk apparatus was used to investigate the effect of sliding speed on the friction, wear, and transfer film characteristics of hemispherically tipped AIST 44OC high-temperature (HT) stainless-steel riders sliding against ultra-high- molecular-weight polyethylene (UHMwPE) disks. The surface morphology of the wear track was studied to determine possible wear mechanisms. Geometry effects were determined by comparing the results to those of others who used different specimen configurations. The results indicate that sliding speed, sliding distance, contact stress, and specimen geometry can all markedly influence the tribological properties of UHMWPE. (MM)
