摘要: Abstract A pin-on-disk tribometer was used, in a comparative test to observe the tribological behavior of swine femoral bone against UHMWPE with dry friction, physiological water and human plasma lubrication. The wear mechanisms bones were investigated by SEM. experimental results these tests demonstrated that both friction coefficient rate lowest when lubrication used. mechanism compact mainly fatigue corrosive under abrasive For UHMWPE, adhesive plastic deformation serious ploughing fracture lubrication, fine An analysis nitrogen elements on surface indicated content worn areas 16 times higher than unworn areas, which proved serum protein deposition occurred areas.
