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 spraying particles of a second material by use of a thermal type spraying process 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 biocompatible material may be cobalt chrome and the carbide source may be graphite. The thermal type spraying process may be a plasma spraying process or a high velocity oxygen fuel spraying process.
