Abstract: A rotating anode structure for an X-ray tube is provided, having a lightweight target anode. A carbon-carbon composite target substrate has constituents and weave geometries. A refractory metal focal track layer is deposited on the substrate to produce X-rays. An interlayer is disposed between the focal track layer and the substrate to relieve thermal expansion mismatch stresses between the carbon-carbon composite anode target substrate and the refractory metal focal track layer. The interlayer is a rhenium interlayer and the focal track layer is typically a tungsten-rhenium focal track layer.

Abstract: The invention relates to a high temperature-resistant composite which consists of at least one part of molybdenum or a molybdenum alloy, and at least one part of graphite, which parts are joined together by means of a zirconium solder. A two-ply interlayer, consisting of a 0.01-0.5 mm thick layer of vanadium, and a 0.1-0.5 mm thick layer of tungsten, tantalum or niobium, is arranged between the part of molybdenum or the molybdenum alloy and the zirconium solder. The layer structure substantially prevents the formation of a eutectic between molybdenum or the molybdenum alloy and the zirconium solder, thereby preventing the reduction of the maximum permissible use temperature of the composite.

Abstract: The invention relates to a rotating anode for an X-ray tube, which avoids the anarchical generation of cracks in a target carried by the anode. For this purpose, at least a part of a target area is carved by a plurality of radial slots arranged symmetrically with respect to an axis of symmetry of the anode. The depth of the slots is less than the thickness of the target.

Abstract: A method for generating X-rays in an X-ray tube, comprises the steps of: rotating an X-ray target of a rotating anode, the X-ray target having a metal coated layer thereon; applying electron beams emitted from a cathode onto the metal coated layer of the X-ray target; and offsetting thermal deformation of the X-ray target due to the application of the electron beams by deformation of the X-ray target due to centrifugal force, thereby maintaining a position of the X-ray target in a direction of the application of the electron beams, at a room temperature of the X-ray target, thus generating the X-rays.

Abstract: An intermediate layer comprising several sub-layers is sandwiched between the support and a target layer of a rotary X-ray anode. The sub-layer of the intermediate layer which contacts the support and the sub-layer of the intermediate layer which contacts the target layer both consist of pure rhenium. Interposed between these two sub-layers is a further sub-layer consisting of a rhenium alloy containing at least one carbide-forming metal, for example tungsten, tantalum or hafnium. This construction of the intermediate layer provides a barrier against carbon diffusion, which barrier has substantially the heat conduction properties of metals and which offers a sufficient protection against the penetration of carbon into the target layer, even at temperaturers above 1500 K.
