Abstract

The surface treatment of ultra-high-molecular-weight polyethylene (UHMWPE) in heliumplasma at a pressure of 0.133 mbar has been studied by IR spectroscopy, X-ray photoelectron spectroscopy,a nd atomic force microscopy. It has been shown that the helium plasma treatment leads to the formation of double bonds in the UHMWPE surface layer and the associated formation of intermolecular crosslinks. The crosslinking of the surface layer is accompanied by a decrease in the nanowear of the UHMWPE surface bymore than three orders of magnitude, which is confirmed by measurements using an atomic force microscope in the contact mode
