    Abstract: According to one aspect of the invention a robust anode structure and methods of making and using said structure to produce ionizing radiation are disclosed. An ionizing radiation producing layer is bonded to the target side of a highly conductive diamond substrate, by a metal carbide layer. The metal carbide layers improves the strength and durability of the bond, thus improving heat removal from the anode surface and reducing the risk of delaminating the ionizing radiation producing layer, thus reducing degradation and extending the anode's life. A smoothing dopant is alloyed into the radiation producing layer to facilitate keeping the layer surface smooth, thus improving the quality of the x-ray beam emitted from the anode. In an embodiment, the heat sink comprises a metal carbide skeleton cemented diamond material. In another embodiment, the heat sink is bonded to the diamond substrate structure in a high temperature reactive brazing process.

    Abstract: Provided are a high-quality and high-reliability rotary anode target for X-ray tubes, of which the mechanical strength at high temperatures is increased and which is applicable not only to low-speed rotation (at least 3,000 rpm) but also even to high-speed rotation at high temperatures, and also a method for producing it. The rotary anode has a two-layered structure to be formed by laminating an Mo alloy substrate that comprises from 0.2% by weight to 1.5% by weight of TiC with the balance of substantially Mo, and an X-ray generating layer of a WnullRe alloy that overlies the substrate.

    Abstract: A rotary X-ray anode has a support body and a focal track formed on the support body. The support body and the focal track are produced as a composite by powder metallurgy. 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: A process for repairing a damaged annular region of an anode configured to emit x-rays includes the step of machining the damaged annular region made of an initial target coating to a depth smaller than a thickness of the coating so as to leave behind a residual annular layer. An intermediate layer is then deposited on the residual annular layer. A repairing layer is then deposited on the intermediate layer. A heat treatment is then performed using an anneal which causes, by interdiffusion and formation of a solid solution, the material of the intermediate layer and the material of the residual annular layer to diffuse into each other and further cause the material of the intermediate layer and the material of the repairing layer diffuse into each other. As a result of this anneal the intermediate layer disappears.
