  • Composite electron beam target for use in X-ray imaging system and method of making same
    Patent number: 4944448
    Abstract: Disclosed is a composite metal structure of a desired configuration and a method of fabricating the composite metal structure by preshaping at least one metal layer prior to assembly of the metal layers in a die of a second preshape configuration. Following brazing of the metal layers while in the die, the brazed structure is removed from the die and springs to the final desired configuration. The process has proved to be particularly useful in fabricating composite electron beam targets for use in X-ray scanners.

  • Emissive coating on alloy x-ray tube target
    Patent number: 4600659
    Abstract: An x-ray tube target composed of a molybdenum alloy material such as TZM is coated with a mixture containing from 40 percent to 70 percent of TiO.sub.2 with the remaining material being a stabilized oxide. The coating is then fused to a smooth, glossy condition to provide an enhanced thermal-emittance surface that adheres well to the target substrate.
