Title
Investigation Of High Emittance Coatings To Extend The Mach Number Range Of Application Of Structural Materials
Description
The value of knowing and being able to modify the thermal emittance of structural materials employed in space and missiles work is well known. This report describes the design and assembly of an apparatus capable of measuring the total and spectral normal emittance of solids at temperatures from 400 to 1800°F, and pressures from atmospheric to less than 5 microns Hg.

Ceramic, paint, oxide and metallic coatings applied to Inconel X, A-286 steel, and 6 Al-4V titanium were investigated.

Emittance data are presented for materials tested after short term, prolonged, and cyclic temperature exposures in the noted temperature and pressure range of the instrument. The effect of contamination is also considered for some materials.

It is show that the emittance of metal substrates can be appreciably altered by the application of suitable coatings.
