Paper Abstract

Coatings with high absorption or emission of thermal radiation are often required in infrared, space and cryogenic applications. It is much more difficult to generate a surface which is sufficiently "black" at cryogenic temperatures than at room or elevated temperatures. An experimental study was carried out to compare the thermal emissivity and absorptivity of a variety of black coatings on copper and aluminum substrates at temperatures in the range from 10 K to 300 K and the results are presented in this paper. The surfaces tested include paints and thin-film coatings.
