Abstract

Friction and wear characteristics of artificial cartilage materials sliding on a smooth metal counterface have been studied in a pin-on-disk apparatus. In this study, polyurethane and polyvinylalcohol (PVA) hydrogel were used as artificial cartilage materials. Synovia constituents, such as hyaluronic acid (HA) and serum proteins (albumin and γ-globulin) were added to saline and their effects on the tribological behavior were examined. As a result, HA and serum proteins exerted a great influence on the friction and wear of artificial cartilage materials. Friction and wear were reduced by HA solution, but were enhanced when serum proteins were added to the HA solution. AFM images showed that a layer of synovia constituents was adsorbed on the counterface, which changed the behavior of material transfer and the wear mechanism of artificial cartilages.
