  • Brazed X-ray tube anode
    Patent number: 9053898
    Abstract: A method (100) creates a braze joint (58) between an anode plate (52) and a piece of graphite (56) of an x-ray tube (38). The method (100) includes receiving (102) the anode plate (52) and the piece of graphite (56). A barrier layer (66) and a braze layer (62) are arranged (104, 106, 108) between the anode plate (52) and the piece of graphite (56), where the barrier layer (66) is between the piece of graphite (56) and the brazing layer (62). The barrier layer (66) is heated (110) with the braze layer (62) to create the braze joint (58) between the anode plate (52) and the piece of graphite (56).
    Type: Grant

  • Anode disk element with refractory interlayer and VPS focal track
    Patent number: 9053897
    Abstract: An anode (30) is formed by building a carbon, such as a carbon reinforced carbon composite, or other ceramic substrate (50). A ductile, refractory metal is electroplated on the ceramic substrate to form a refractory metal carbide layer (52) and a ductile refractory metal layer (54), at least on a focal track portion (36). A high-Z refractory metal is vacuum plasma sprayed on the ductile refractory metal layer to form a vacuum plasma sprayed high-Z refractory metal layer (56), at least on the focal track portion.
