INVESTIGATION OF THE EFFECT OF SURFACE CONDITION ON THE RADIANT PROPERTIES OF METALS

Abstract

Results are presented on the optical and radiant properties of copper, platinum and tungsten. Optical constants n and k are presented as a function of temperature and wavelength, and the method for their determination is described. Radiant properties reported include the total and spectral emittance as a function of emission angle, polarization, temperature, and surface roughness. Methods are described for the evaluation of surface geometry, and results obtained on all test samples are presented. Profilometry, metallographic inspection, x-ray diffraction, and spark spectroscopy were employed for evaluation of surface condition and are discussed in terms of their utility for this program. Theories of the scattering of electromagnetic waves from a rough surface are briefly reviewed and necessary extensions of present theories to an emitting surface are indicated.
