An yttrium fluoride sprayed coating having a thickness of 10-500 μm, an oxygen concentration of 1-6 wt %, and a hardness of 350-470 HV is deposited on a substrate surface. The yttrium fluoride sprayed coating exhibits excellent corrosion resistance in a halogen-base gas atmosphere or halogen-base gas plasma atmosphere, functions to protect the substrate from damage by acid penetration during acid cleaning, and minimizes particle generation from a reaction product and due to spall-off from the coating.

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.
