Abstract:
Results obtained for the spectral emittance of materials measured in air at intermediate temperatures of about 1400°F are compared to the spectral reflectances measured at room temperature to provide an appraisal of the effect of temperature on those radiation properties.. The temperature effect is found to be small for oxidized metals and for ceramic coatings and some of the apparent effects are still associated with variation of the material and with inaccuracy of measurement. Spectral emittances for metals were determined only for platinum.; these results and those of other investigators are analyzed to show that the apparent coincidence in the applicability of that formulation to the specification of the total emittance. A system designed for the determination of the spectral emittance of metals or of materials with metallic substrates, in vacuum or in an inert atmosphere, is described and preliminary results are indicated for Inconel. Spectral and total properties of various materials obtained in certain tasks are also presented, this comprising particularly the properties of ceramic coatings prepared by the Chance-Vought Company.
