Abstract:
1. Method of fabricating a material having a high concentration of a carbide constituent and utilizing said material to coat at least one surface of a medical implant component, said method comprising: adding a carbide source to cobalt chrome or an alloy thereof, in which a weight of the carbide source is at least approximately 50% of a total weight of the carbide source and the cobalt chrome or the alloy thereof; heating the carbide source and the cobalt chrome or the alloy thereof to a predetermined temperature to melt the cobalt chrome or the alloy thereof and allow the carbide source to go into solution so as to form a molten homogeneous solution; and impinging the molten homogeneous solution with a high pressure fluid so as to form spray atomized powder having carbide particles, in which a size of a carbide particle in the atomized powder is approximately 900 nanometers or less, and coating the at least one surface of the medical implant component with the spray atomized powder having carbide particles, in which the medical implant component is configured as an acetabular cup, a femoral head, a femoral knee, a tibial knee, a shoulder component, or a spine component.
