Abstract:
A composite substrate for use in a rotating x-ray anode tube consists of a graphite member joined to another member to which a target anode is affixed.
Abstract:
A graphite disc assembly for a rotating x-ray tube embodying a graphite substrate and an anode target of either tungsten or tungsten rhenium joined thereto by a layer of rhodium, osmium, ruthenium, platinum, platinum-chromium, or palladium.
Abstract:
Methods for the diffusion bonding of a graphite member to a metallic surface as part of a composite rotary anode for an X-ray tube are set forth. The preferred joint for the composite is made by using a layer of palladium in combination with a layer of metal selected from the group consisting of platinum, osmium, rhodium, ruthenium and alloys thereof.
Abstract:
Tungsten anode targets are joined to graphite substrates by a brazing method employing a .[.controlled.]. .Iadd.hydrogen .Iaddend.atmosphere and a suitable braze material such as platinum and an alloy of platinum and chromium.
Abstract:
A method for the diffusion bonding of a graphite member to a metallic surface of molybdenum, molybdenum alloy, tungsten or tungsten alloy as part of a composite rotary anode for an X-ray tube is set forth. In the completed structure a crack-free compound laminate separating and joining the graphite member and the metallic surface comprises a layer of carbide of metal of the metallic surface bonded to a layer of platinum or platinum alloy.
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.
