摘要： A composite body for rotary anodes of X-ray tubes is made from graphite, a carbide-forming, high-melting metal component and a multi-layered intermediate layer. The first layer of the intermediate layer closest to the graphite is made up of a metal or an alloy thereof which does not form a carbide. Applied over the first layer are at least two double layers. Each double layer has one individual layer of at least one carbide-forming metal or at least one carbide thereof, and a second individual layer of a metal or an alloy thereof which does not form a carbide. Preferred carbide-forming metals are tungsten, tantalum, hafnium and niobium. Preferred metals which do not form carbides are rhenium and platinum. In a preferred embodiment, the composite body is a rotary anode for X-ray tubes, with a basic body made of graphite and a burning track made of tungsten or a tungsten-rhenium alloy applied directly to the intermediate layer.

摘要： The invention pertains to a method for manufacturing a rotary anode assembly for an X-ray tube. According to the invention, a base element made of graphite is joined in a first step as a blank with excess dimensions to a shaft by material bonding. Then the further processing of the rotary anode assembly takes place by mechanical machining to nearly final-form dimensions and by application of the focal track coating, wherein the axis of rotation of the shaft is utilized as the reference for the performance of the mechanical machining.

摘要： The invention relates to a method of producing an X-ray rotary anode having a focal track region composed of refractory metals. The focal track region is manufactured by means of powder-metallurgy methods or by means of CVD or PVD methods. According to the invention, the focal track region is posttreated using high-energy electrons or photons by means of local, superficial melting to a depth of less than 1.5 mm. This reduces, in particular, the residual porosity in the focal track region. That results in improved mechanical properties, higher X-ray yield and markedly improved service life of such rotary anodes.
