Abstract: The biological friction and wear properties of UHMWPE rubbing against SiC ceramics lubricated with fresh plasma were evaluated by using Falex at 37℃, and the surfaces of the specimenwere observed with SEM and surface profile meter. The results show that the friction coefficient of UHMWPE against SiC is about 0.05, and the wear factor of UHMWPE is lower than8.45×10--10mm3/N.m. The wear loss of SiC ceramics is very small. Based on the results of XPSanalysis, the mechanism was proposed.

Key words: ultrahigh molecular weight polyethylene(UHMWPE), SiC ceramics, plasma, biotribologicaJ properties and mechanism
