Abstract (en)
[origin: EP2194564A1] The x-ray target assemblies (100) have an oxide dispersion strengthened (ODS) refractory metal alloy substrate (110) that is bonded to a carbon-containing heat sink (116). 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 (124) between the ODS metal substrate and the heat sink. The oxide-free barrier layer (124) 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.
