Abstract:
A metal matrix has a biocompatible solid lubricant in at least a portion of its surface and the solid lubricant functions to protect the interior of the metal matrix and minimize the friction coefficient and related wear induced damage at the articulating surface of the metal device. The lubricated biocompatible metal device is made of materials compatible for in vivo and ex vivo applications in order to minimize wear induced degradation as well as metal ion release. The lubricated biocompatible metal device is suited for use as medical implants.
