Analysis of biobearings friction and wear processes

The paper draws up some issues connected with processes of friction and wear of bio-bearings. The non-Newtonian liquid lubrication in joints can be presented in tribological models. Considering a proper friction model allows us to mathematically stipulate the resistances that occur in natural joints. The paper includes empirical results of the analysis conducted to designate parameters of cooperation between the tissue and implanted materials. Friction resistances in modelled sets as well as curves of the wear have been assigned for the friction pairs.
