Abstract
Electron emission from an emissive substance, such as an emissive composite material, can be employed as a heat dissipation technique and mechanism for a part subject to operational heating. Emissive composite materials containing a refractory metal matrix and a ceramic electride material in the refractory metal matrix can be utilized for this purpose. Emissive composite materials can retain the thermal stability of the base refractory metal and emit electrons upon being heated to a sufficiently high temperature. Cooling systems and associated methods can utilize a collector configured to receive electrons emitted across open space by the ceramic electride material upon heating, and a conductive pathway can allow the electrons to be returned to the emissive composite material. Accordingly, the emissive composite material and the collector define a portion of an electrical circuit.
