    Abstract: An X-ray emitting target including a diamond substrate (80), a first layer (81) disposed on the diamond substrate and including a first metal, and a second (82) layer disposed on the first layer and including a second metal whose atomic number is 42 or more and which has a thermal conductivity higher than that of the first metal. The layer thickness of the first layer is greater than or equal to 0.1 nm and smaller than or equal to 100 nm. The target is prevented from overheating, so that output variation due to rising temperature is suppressed. Thus it is possible to emit stable and high output X-rays.

    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: An anode for an X-ray tube can include one or more of an yttrium-oxide derivative, titanium diboride, boron carbide, titanium suboxide, reaction-bonded silicon carbide, and reaction-bonded silicon nitride. Upon collision with an anode, the kinetic energy of an electron beam in an X-ray tube is converted to high-frequency electromagnetic waves, i.e., X-rays. An anode from one or more of the above materials and a gradient distribution of conductive metals can reduce costs and/or weight, extend the life of the anode or associated components (e.g., bearings) and simultaneously provide a higher heat storage capacity as compared to traditional molybdenum and tungsten anodes.
