Abstract

Surface modification of ultra high molecular weight polyeththylene (UHMWPE) was explored using ion implantation with diffferent dosages (1 X 10(15)-1 X 10(17) ions cm(-2)) of nitrogen. The modified surfaces it.-ere characterised by SEM, nanoindentation and tribological tests. The experimental results showed that ion implantation can significantly increase the surface hardness of UHMWPE. However, the improvement in it-ear resistance of the modified UHMWPE is highly dose dependent. Compared with the untreated material, the low dose implanted UHMWPE exhibited a three fold improvement in wear resistance, while the high close ion implanted material showed hardly any improvement although it possessed the highest hardness.
