Abstract:

Most surface emissivity coatings exhibit adherence problems under there severe operating conditions of an arcjet. A porous surface produced from powdered tungsten would more than double the effective emissivity, and would maintain full metallurgical integrity with the tungsten anode. Certain coatings, specifically hafnium carbide, appear promising and will be investigated. Combining hafnium carbide with porous tungsten could produce an effective emissivity in excess of 0.98.
