<p>This invention relates to wear components having synthetic diamond wear surfaces, and more particularly, to diamond-coated wear components, and to a method of making such components. It uses a layered diamond film structure which reduces or eliminates the need for polishing the diamond surface after deposition of the diamond film. The smooth surface characteristic of (100) orientation diamond is used to advantage, without the accompanying low wear resistance property, by depositing a different orientation (111) diamond and then depositing an exceedingly thin top layer of (100) orientation diamond. Said second layer will preferably have the minimum thickness required to overgrow the rough underlayer, and to provide a smooth free-surface of the diamond film.</p> |
