ABSTRACT:
A rotary anode for an X-ray tube comprising an anode body formed of graphite, a target layer formed of tungsten or alloy thereof, and an intermediate layer containing rhenium and molybdenum, the intermediate layer being interposed between and bonded with the anode body and target layer. This rotary anode may be obtained by forming over a target area of the graphite anode body a paste layer containing rhenium powder and molybdenum powder, laminating over the paste layer a layer formed of tungsten or alloy thereof, and then hot-pressing the resultant laminated body under vacuum or in an inert gas by means of a pressure transmitting powder.
