Abstract: A structure and associated process for joining dissimilar materials to form various components of an x-ray tube is illustrated that utilizes one or more intermediate or interfacial filler material members positioned between the primary welding or mating surfaces of the base material components to be joined. The use of the interfacial or intermediate filler material preserves the multiple benefits of friction welding, as well as enabling the joining of highly dissimilar material components, decreasing the required joining temperature, and providing increased microstructural control of the resulting weld or joint.

Abstract: A system and method for x-ray tube components is disclosed. The method of fabricating an x-ray tube component includes providing a powder into an electrically conductive die constructed to have a cavity shaped as the x-ray tube component being fabricated and simultaneously applying a mechanical pressure and an electric field to the die so as to cause sintering of the powder and thereby fabricate the x-ray tube component, wherein the electric field applied to the die directly passes through the die to the powder, so as to generate heat internally within the powder responsive to the applied electric field.
