COATED REFRACTORY METAL EMITTANCE SPECIMENS.
Abstract
Four columbium base alloys were coated with oxidation resistance coatings by four different industrial organiza tions and submitted to the American Machine and Foundry Company for measurement of thermal radiation and other general physical properties at 1520F. Basic acceptance data obtained for these four coated-columbium base alloys included photomicrographs of the coatings before and after a six (6) hour stability test, physical observation of the stability of the coatings at 2500F at hourly intervals to a maximum of six (6) hours, surface roughness measurements, and such thermal optical data as total normal emittance, spectral emittance and spectral reflectance. Companion specimens of the four columbium alloys coated by the four different organizations were submitted to the Materials Applications Division of RTD for their in-house thermal radiation physical property studies.
