The cathode includes an intermediate x-ray target assembly upon which the metal is to be deposited and/or an electrically conductive mold for forming a component of an x-ray target assembly. The x-ray target component (e.g., a substrate or focal track) is formed by submersing the cathode in the electrolyte and applying a voltage across the anode and the cathode to cause the metal from the anode to be electroformed on the intermediate target and/or the mold. The electroforming is continued until a desired thickness of metal is achieved.

The x-ray target assemblies have excellent bonding between the substrate and the heat sink. The improved bonding is achieved by placing an oxide-free barrier layer between the ODS metal substrate and the heat sink. The oxide-free barrier layer minimizes or eliminates chemical reactions that would otherwise be possible between the dispersed oxides and the carbon-based heat sink during the manufacturing process. Preventing these undesired reactions while manufacturing the x-ray target assembly yields a device with improved bonding between the heat sink and the substrate, compared to devices manufactured without the barrier layer. | 10-21-2010 |
