Work in support of NASA space power systems is reported in which an aluminum phosphate-bonded coating completed 3800 hours of endurance on a SNAP-8 finnedtube radiator segment. Plasma flame-sprayed coatings of titania on SNAP-8 and Sunflower I sections completed 1400 hours. A fourth rig containing a SNAP-8 section with an aluminum phosphate-bonded coating accumulated 120 hours. Total emittance was measured on coatings of zirconium silicate on stainless steel strip, Rokide C on stainless steel tube, titania base powder on aluminum strip and on stainless steel strip, aluminum phosphate bonded with boron and silica on aluminum strip, aluminum phosphate bonded with silicon carbide and silica on aluminum strip, ceric oxide on stainless steel strip, acetylene black in xylol on aluminum strip, titania on aluminum strip, strontium titanate on stainless steel strip, oxidized stainless steel, and titania-alumina on stainless steel. Endurance testing was conducted on the Rokide C, oxidized stainless steel, and titania-alumina on stainless steel. (auth)
