  • Heat radiating coating and method of manufacture thereof
    Patent number: 3982148
    Abstract: A heat radiating coating of rhenium for a refractory core which may be used for a rotating X-ray anode, power tube or the like. The coating is characterized by a multiplicity of needle-like radiation-reflecting elements disposed adjacent to each other. The needles have such steep angles that incoming radiation is substantially absorbed thereby by repeated reflection. Since the coating has a high radiation absorption coefficient it has a corresponding high emissivity on the order of 0.9 at elevated temperatures. A process is disclosed for depositing such a heat radiating coating of rhenium by chemical vapor deposition.
