EVALUATION OF INCREASE CROSSLINKING DENSITY ON MECHANICAL AND TRIBOLOGICAL PROPERTIES OF GUR 1050 POLYETHYLENE USED FOR ENDOPROSTHESIS CUPS SHAPED BY ELECTRON BEAM IRRADIATION AND PLASTIC DEFORMATION
Journal Title: Tribologia - Year 2014, Vol 254, Issue 2
Abstract
Radiation modification with subsequent plastic deformation was conducted in order to increase the resistance of GUR 1050 polymer to plastic deformation and wear. Electron irradiation of 26-156 kGy dose and plastic deformation of the value of ef = 0.2 was applied. It was determined that the crosslink density increase along with the increase of the dose of radiation. It was also found that there is a close relationship between the crosslink density and the mechanical and tribological properties. Tribological tests conducted on the T-05 and T-01 testers have shown that the increase of crosslink density after electron beam irradiation and subsequent plastic deformation result in a 13-fold reduction in linear wear and a 6-fold reduction mass wear as compared to unmodified polyethylenes. The obtained results demonstrate the effectiveness of the technology used for the modification the polymer, which promises the possibility of extending the lifetime of endoprosthesis cups.
