THE EFFECT OF AN ACCELERATED AGEING PROCESS ON TRIBOLOGICAL WEAR OF POLIMERIC ELEMENTS IN JOINT ENDOPROSTHESES
Journal Title: Tribologia - Year 2016, Vol 266, Issue 2
Abstract
The polymeric components of endoprostheses in in vivo conditions are subjected to the oxidation process (ageing). The paper presents the results of friction and wear testing performed with use of a knee-joint simulator. The polymeric parts were machined from UHMWPE and UHMWPE modified with the addition of vitamin E. The calorimetric analysis and tribological testing results confirm the negative effect of accelerated ageing in oxygen atmosphere on the tribological properties of UHMWPE as well as the antioxidative properties of vitamin E.<br/><br/>
