Abstract
An X-ray anode, in particular a rotary anode, having a parent body made of a carbon-containing refractory material. To improve the thermal radiation characteristics of the anode, the anode is provided with an oxidic top layer outside the focal spot or the focal track regions which contains a homogeneously fused phase. A two-ply interlayer arrangement, containing a first-ply of molybdenum and/or tungsten, and a second oxidic ply of Al.sub.2 O.sub.3, containing 1-30% by weight of TiO.sub.2, is arranged between the parent body and the oxidic top layer. As a result of this interlayer structure, the fusion of the oxidic top layer so as to form a homogeneous phase becomes possible without problems. In addition, the ageing resistance of the thermal emission coefficient ('.epsilon.') is substantially improved.
