Abstract: A rotary anode for an X-ray tube, the anode body consisting essentially of graphite, and having a target layer bonded thereto consisting essentially of a tungsten-rhenium alloy; in an alternate embodiment, to improve the bonding between the target layer and the anode body, a thin stratum consisting essentially of rhenium is interposed between the anode body and the tungstenrhenium target layer; AND PROCESSES OF UNITING THE TARGET LAYER TO THE ANODE BODY, INCLUDING DEPOSITING THE TUNGSTEN AND RHENIUM LAYER ON THE ANODE BODY OUT OF A GAS PHASE, AND DEPOSITING THE INTERMEDIATE RHENIUM LAYER BETWEEN THE TARGET LAYER AND THE ANODE BODY OUT OF A GAS PHASE.

Abstract: This invention relates to a rotating X-ray target made up of three metallic components, i.e., a molybdenum body, a focal track of an alloy of tungsten with one or more metal additives and a component present in the surface not exposed to electrons comprising tungsten alone or a tungsten alloy having a lesser amount of the additive metals.
