Abstract

It was found that a film, about 1250 angstroms thick, of gold, rhodium and oxides of bismuth, barium, chromium and silicon could be reproducibly obtained on a variety of diffusion barriers on Inconel. This was done by a signle brush or spray application of an organic solution, followed by thermal decomposition in the air. Total reflectance measurements before and after samples were subject to elevated temperatures in high vacuum indicate that on vacuum deposited cerium oxide the gold-plus-oxides film is essentially unchanged after 50 hours at 800 C in a vacuum of 0.3 x 10 to the -5th power torr. Under the same conditions of time and vacuum at 600 C, the film is unchanged over diffusion barriers obtained from National Bureau of Standards Frit A-418 and over films of cerium oxide about 1000 angstroms thick obtained by thermal decomposition of organic compounds. Reflectance of the film at wavelengths below 1.5 microns can be decreased by overcoating with a film of aluminum oxide about 1000 angstroms thick.
