Abstract
A rotary x-ray anode with an integrated liquid metal bearing outer shell has an anode disc made of Mo or a Mo-based alloy formed with a hole, which is formed centrally in the region of the axis of rotation and extends in the axial direction at least through part of the anode disc, and a bearing bushing made of Mo or a Mo-based alloy. The bearing bushing is connected to the anode disc via a material bond and its inner wall extends the hole in the anode disc. At least an axial portion of an inner wall of the hole in the anode disc and at least an axial portion of an inner wall of the bearing bushing are formed circumferentially as a liquid metal bearing running surface and they form at least a part of a liquid metal bearing outer shell. There is also described a corresponding production method.
