The invention relates to a graphite composite consisting of a carbide-forming refractory metal component and of a multi-ply interlayer. …<??>The first ply of the interlayer, adjoining the graphite, consists of a metal which does not form a carbide, or alloys thereof. …<??>Adjoining this ply, at least two double plys, i.e. in each case one ply of one or more carbide-forming metals or of carbides or mixed carbides thereof and a ply of a metal which does not form carbide, or alloy thereof, are arranged. …<??>Preferred carbide-forming metals are tungsten, tantalum, hafnium or niobium. …<??>Preferred metals which do not form carbide are rhenium or platinum. …<??>A preferred embodiment of a composite according to the invention is a rotary anode for X-ray tubes having a base body of graphite and a focal track, applied directly to the interlayer, of tungsten or a tungsten/rhenium alloy. |
