An increase in the application potential of the ultra-high molecular weight polyethylene (UHMWPE) may be achieved by producing a hard, wear resistant carbonaceous modified surface layer on it. In this study the surface of UHMWPE samples was treated by 1 keV N, H and He fast atom bombardment (FAB) to obtain amorphous carbon surface layer which produces an enhancement of microhardness. The untreated...
Plasma-based ion implantation was used to modify the surface of ultra-high molecular weight polyethylene. High-purity N 2 , He and H 2 gases were ionized in radio frequency (rf) discharge and implanted at acceleration voltages of 20–30 kV with dose of 2×10 17 ion/cm 2 . The first-order Raman spectra with probe wavelengths of 785 nm and 488 nm as well as infrared reflection...
