Abstract: Disclosed is an improved composite anode for rotating-anode xray tubes and an improved method of fabrication thereof. The anode comprises a substrate disk, a portion of whose focal track is scored, for example by scratching or engraving of one or more annular grooves of rectangular cross-section. A coating of x-ray emissive material covers the scored region. In certain embodiments of the invention, the emissive coating is undercoated with an interlayer of a material which is a poor emitter of xrays. The emissive coating and/or the undercoating may cover other portions of the disk and, in particular, may cover all exposed surfaces thereof. The method comprises providing such a disk, scoring it in the focal track region and applying an x-ray emissive coating to the scored region. The last step may be preceded by the application of an undercoating of a material which is a poor x-ray emitter. Either or both coatings may be applied to other surfaces of the disk.
