ABSTRACT:
The present invention is directed to an air-cooled radiographic apparatus, and its method of manufacture, that utilizes a single integral housing for providing an evacuated envelope for an anode and cathode assembly. The integral housing is preferably formed from a substrate material that has a radiation shielding layer comprising a powder metal that is deposited with a plasma spray process. The powder metal includes, for example, tungsten and iron, so that the radiation shield layer provides sufficient radiation blocking and heat transfer characteristics such that an additional external housing is not required. In one alternative embodiment, the integral housing is composed of a solidified, integrated mixture of metallic powders that function together as both the integral housing wall and the radiation shielding. In another alternative embodiment, chromium is intermixed into the mixture of metallic powders to form a thermally emissive surface upon firing the housing in a wet hydrogen environment.
