Abstract (en)
[origin: EP0488450A1] In an X-ray anode, in particular a rotary anode having a parent body consisting of a refractory material containing carbon, the anode is provided with an oxidic top coating containing a homogeneously fused phase outside the focal spot or the focal track to improve the heat radiation. Situated between the parent body and the oxidic top layer is a two-layer interlayer containing a layer of molybdenum and/or tungsten and a layer of Al2O3 containing 1 - 30 % by weight of TiO2. It is only this interlayer which makes it possible to fuse the oxidic top layer satisfactorily to form a homogeneous phase. In addition, the ageing resistance of the thermal emission coefficient is substantially improved.
