Abstract
A method for the diffusion bonding of a graphite member to a metallic surface as part of a composite rotary anode for an X-ray tube is set forth. In the completed structure a compound laminate separating and metallurgically bonded to the graphite member and to the metallic surface consists of, in sequence, a layer comprising carbide of vanadium and of a metal selected from the group consisting of molybdenum and tungsten, a layer of metal selected from the group consisting of vanadium and vanadium alloys, a zone of interdiffused metals comprising platinum and vanadium and then a continuous layer comprising platinum or platinum alloy.
