Abstract

Metal-on-metal (MoM) hip joints are recommended in modern total hip replacement surgery for their excellent wear resistance. But they still suffer the result from biotribocorrosion processes which lead to the release of metal ions and debris. The microstructure of the joint surface is a key factor for the safety of MoM joints. In this study; a layered structure that formed on the MoM joint surface under simulated conditions was found. The layered structure was investigated by SEM, TEM and EDX. The result shows that the layered structure contain a carbon-rich film, a organometallic film and a nanocrystalline layer. The evolution process of the joint surface was also proposed.
