Abstract

This report deals with comparison of the total hemispherical reflectances (THR), emissivities, and solar radiation absorption factors of coatings designed to reduce a stray light background and provide the thermal control both in space-based instruments and in land-based equipment. The THR measurement results are presented that have been carried out at 10 values of wavelengths within visible, near- ultraviolet, and near-infrared ranges (400 to 927 nm). The coatings being compared are as follows: chemically oxidized copper, coating on the basis of Al-N system, black-chromium coating, black bituminous paint, commercial black enamel used in solar converters, and plasmatron sputtered nichrome and constantan alloys. The chemically oxidized copper has been chosen as a material possessing high solar radiation absorption factor and low emissivity. Black-chromium coating is a widespread material for thermal control in space instruments. The black bituminous paint has been chosen as a possible cheap alternative solar absorber. Commercial black enamel served as a standard conventional coating used in some inexpensive solar converters. Nichrome and constantan have been also selected for investigations as the alloys having high specific resistivities, which promised that intensive electron scattering in skin layers of these alloys could take place, i.e., intensive transfer of energy and momentum received from the light wave to the lattice.
