摘要: A medical implant component and a method for fabricating the same are provided. The medical implant component may comprise a substrate having a bearing portion, in which at least the bearing portion has a coating of at least 25 micrometers of a predetermined material. The predetermined material of the coating may include chromium ceramic having a chromium component which releases less than approximately 7 parts of hexavalent chromium per billion parts of water solution when the medical implant component is immersed in approximately 500 milliliters of water for approximately one week at a temperature in a range of room temperature to just below a boiling point of the water at atmospheric pressure. The residual stress of the coating may be less than approximately 100,000 pounds per square inch. The chromium ceramic may be a chromium oxide, a chromium carbide, a chromium nitride, or a chromium boride, or any combination thereof.
