Abstract


Influence of Mechanical Activation (MA), Chemical Modification (ChM), Ion Implantation (IIm) and adding different size fillers (nano- and micro) onto physical-mechanical and tribotechnical properties of Ultra High Molecular Weight Polyethylene (UHMWPE) are investigated. By means of X-ray diffraction, IR-spectroscopy, DSC and SEM the structure and wearing pattern for a number of UHMWPE-based composite enforced by С and Al2O3 nanofibers, Сu и SiO2 nanoparticles, Al2O3 и AlO(OH)) microparticles were examined. Comparison of different ways of modification of UHMWPE binder to obtain composites on its basis is carried out. The mechanism to explain high wear resistance of composites with high-molecular weight matrix is discussed.
