Abstract
A method of fabricating a material having a high concentration of a carbide constituent. The method may comprise adding a carbide source to a biocompatible material in which a weight of the carbide source is at least approximately 10% of the total weight, heating the carbide source and the biocompatible material to a predetermined temperature to melt the biocompatible material and allow the carbide source to go into solution to form a molten homogeneous solution, and impinging the molten homogeneous solution with a high pressure fluid to form spray atomized powder having carbide particles. The size of a particle of carbide in the atomized powder may be approximately 900 nanometers or less. The biocompatible material may be cobalt chrome, the carbide source may be graphite, and the fluid may be a gas or a liquid.
