  • High emissive coatings on x-ray tube components
    Patent number: 6456692
    Abstract: An x-ray tube having one or more components, such as the rotor, that include a coating of relatively high emissivity. The coating, a metal oxide composition for example, is selectively applied to desired portions of the component by plasma spray or similar process. The relatively high emissivity of the coating enhances the ability of the coated surface to radiate heat, and thereby aids in implementation of a cooling effect with respect to the x-ray tube.
