摘要： 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.

摘要： A method and an apparatus for locally applying material to the surface of an anode of an X-ray source as well as a corresponding anode is presented. Anode material such as a repair material for filling a recess (121) in an X-ray emitting surface (115) is applied to the X-ray emitting surface of an anode (101). The location where such material is to be applied may be detected using a laser beam (133). The applied repair material including particles (41) of anode material such as tungsten, rhenium or molybdenum, is subsequently locally sintered using a high-energy laser beam (151). The sintered material may then be melted using a high-energy electron beam (163). Using such method, a damaged surface of an anode may be locally repaired. Alternatively, structures of different anode materials or of protrusions having different levels can be provided on the X-ray emitting surface (115) in order to selectively manipulate the X-ray emitting characteristics of the anode (101).

摘要： The present invention relates to a method for providing a molybdenum-molybdenum or molybdenum aaloy-molybdenum alloy brazing. In accordance with the invention this method comprises the following steps: - providing at least two parts (16, 22) made of molybdenum or a molybdenum alloy; - brazing together said two parts (16, 22) using a brazing material (26); and - providing a plasma-sprayed molybdenum of molybdenum alloy layer (28) at least on a portion of the brazing material (26) that would be accessible otherwise. Furthermore, the present invention is directed to a rotary-anode X-ray tube (14) which is equipped with a spiral groove bearing (12) comprising, as a first part (16), an axle blank (16) having a center bore (18) and being made of molybdenum or a molybdenum alloy and, as a second part (22), a cap (22) made of molybdenum or an molybdenum alloy, wherein, for closing one open axial end (24) of said axle blank (16), said axle blank (16) and said cap (22) are brazed together using the method in accordance with the invention.

摘要： 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.
