Patent ID: 7771775

Claim:
A method of fabricating a medical implant component, said method comprising: producing a substrate from a first material, said substrate having a bearing portion; and spraying particles of a second material using a thermal type spraying process onto at least the bearing portion of the substrate, said second material being formed from a biocompatible material and a carbide, in which the carbide content is 6.17% or more of the second material by weight, the carbide is a chrome carbide, the chrome carbide is in the form of Cr 23 C 6 , an average size of a particle of the carbide has a size of approximately 900 nm or less, and the biocompatible material is cobalt chrome, titanium, a titanium alloy, zirconium, a zirconium alloy, stainless steel, or a cobalt based super alloy, wherein upon completion of the fabrication, the bearing portion is a bearing surface which is operable to articulate with a portion of a bone or another medical implant component.
