Abstract

PTFE specimens were slid against an EN24 disc. The unworn and worn surfaces as well as the wear debris were examined by X-ray diffraction. Sliding was found to introduce (i) shrinkage of the unit cell, (ii) enlargement of crystallites and (iii) residual stresses in the slid PTFE13; surface. No conformational changes in the 15, helix could be observed due to sliding. The wear debris was found to be 1 pm thick warped laminates.
