Abstract: A system and method for x-ray tube components is disclosed. The method of fabricating an x-ray tube component includes providing a powder into an electrically conductive die constructed to have a cavity shaped as the x-ray tube component being fabricated and simultaneously applying a mechanical pressure and an electric field to the die so as to cause sintering of the powder and thereby fabricate the x-ray tube component, wherein the electric field applied to the die directly passes through the die to the powder, so as to generate heat internally within the powder responsive to the applied electric field.

The support body is formed from molybdenum or a molybdenum-based alloy and the focal track is formed from tungsten or a tungsten-based alloy. Here, in the conclusively heat-treated rotary X-ray anode, at least one portion of the focal track is located in a non-recrystallized and/or in a partially recrystallized structure.

Abstract: The present invention refers to hybrid anode disk structures for use in X-ray tubes of the rotary anode type and is concerned more particularly with a novel light weight anode disk structure (RA) which comprises an adhesion promoting protective silicon carbide (SiC) interlayer (SCI) deposited onto a rotary X-ray tube's anode target (AT), wherein the latter may e.g. be made of a carbon-carbon composite substrate (SUB′). Moreover, a manufacturing method for robustly attaching a coating layer (CL) consisting of a high-Z material (e.g. a layer made of a tungsten-rhenium alloy) on the surface of said anode target is provided, whereupon according to said method it may be foreseen to apply a refractory metal overcoating layer (RML), such as given e.g. by a tantalum (Ta), hafnium (Hf), vanadium (V) or rhenium (Re) layer, to the silicon carbide interlayer (SCI) prior to the deposition of the tungsten-rhenium alloy. The invention thus leverages the tendency for cracking of the silicon carbide coated carbon composite substrate (SUB′) during thermal cycling and enhances adhesion of the silicon carbide/refractory metal interlayers to the carbon-carbon composite substrate (SUB′) and focal track coating layer (CL) by an interlocking mechanism. Key aspects of the proposed invention are: a) controlled formation of coating cracks (SC) in the silicon carbide layer (SCI) and b) conformal filling of SiC crack openings with a refractory metal.

Abstract: The present invention relates to X-ray generating technology in general, in particular, it relates to an anode disk element (1) for an X-ray generating device (21). The generation of electromagnetic radiation may be considered to be quite inefficient, since a substantial part of energy applied to a focal track is converted to heat rather than X-radiation. Thus, a limiting factor in the operation of X-ray tubes is the cooling of the anode element and more specifically the focal track. In the present invention, an anode disk element is provided, with an improved dissipation of heat from the focal track. Thus, the anode disk element may sustain increased heat while maintaining structural integrity. The anode disk element (1) comprises at least a first surface (2) and a second surface (3), with the first surface (2) comprising a focal track (4) and the second surface (3) comprising a conductive coating (5). The anode disk element (1) is rotatable about a rotational axis (6) with the focal track (4) being rotationally symmetrical to the rotational axis (6). The first surface (2) comprising the focal track (4) and the second surface (3) comprising the conductive coating (5) are adjacently arranged.

Abstract: An x-ray tube and method of operating include a vacuum chamber vessel and a source of an electron beam inside the vacuum chamber vessel. A target disposed inside the vacuum chamber vessel includes a substrate and one or more deposits attached to the substrate. Each different deposit includes an atomic element having a different atomic number. The x-ray tube also includes a means for directing the electron beam to a selectable deposit of multiple deposits. The substrate material can be selected with better vacuum sustaining strength, x-ray transparency, melting point, and thermal conductivity than a deposit. The substrate may be cooled by an integrated cooling system. The x-ray tube allows a selectable x-ray frequency to be produced with enhanced economy of power, reduced moving parts, and reduced size. For improved bone mass applications, one of the deposits has a k-fluorescence energy less than about 53 thousand electron volts.

Abstract: A brazed X-ray target includes a metallic cap and a graphite back including a nonlinear record groove attached thereto along a stepped surface. An upper corner joint of the stepped surface is distanced from a cap outer edge and a focal track where the maximum heat is generated during use of the target. The graphite back is extended outward toward the cap outer edge to increase a thermal storage of the graphite, and a recess is formed into the cap to maintain a selected moment of inertia of the target and thereby maintain the rotordynamics of a given X-ray tube.

Abstract: The present invention is directed to an x-ray tube, and method of manufacture thereof, having an improved rotary anode target structure. The anode target is constructed of carbon-carbon composite material. A focal track is formed on the surface of the anode target, and is comprised of a metallic material that is capable of generating x-rays when contacted with a high velocity electron stream. The surface of the carbon-carbon composite anode is treated in a manner so as to provide an enhanced bond between the composite and the focal track material, and which diffuses any interfacial stresses that occur between the track layer and the composite substrate during thermal expansion of the two materials, which may differ significantly. In particular, the bond interface is formed by microscopically roughening the surface of the substrate, so as to provide a “saw-tooth”-like, or jagged, surface configuration. This provides a high surface contact area per unit length between the composite and the focal track material, thereby diffusing any stresses resulting from thermal expansion of the two materials. This jagged bond interface surface is formed by removing carbon atoms from the composite surface by way of an oxidization process, such as thermal etching. In addition, the surface of the composite may also be mechanically etched, such as laser etching, to further provide a roughened surface.
