ABSTRACT:
A method of fabricating a medical implant component. The method may comprise producing a substrate from a first material in which the substrate has a bearing portion, and causing particles of a second material to be formed onto at least the bearing portion of the substrate. The second material may be formed from a biocompatible material and a carbide source, in which the carbide source is 6.17% or more of the second material by weight. The particles of the second material may be formed onto at least the bearing portion of the substrate by a predetermined spraying technique, a CVD process, a PVD process, or a carburization process. The biocompatible material may be cobalt chrome and the carbide source may be graphite.
