Abstract
An x-ray tube having a coated x-ray tube frame inner surface and a coated anode assembly is provided. The x-ray tube includes an x-ray tube frame in which an anode assembly is disposed therein. A cathode assembly is also disposed within the x-ray tube frame that emits an electron beam to strike a target surface of the anode assembly and form x-rays. A plasma-sprayed tungsten oxide coating is formed on an inner surface of the x-ray tube frame and on the anode assembly to dissipate heat created by the electron beam.
