Abstract:

The suitability of solar absorber coatings for use as the thermal power source to drive spaceborne Vuilleumier cycle cryogenic refrigerators was evaluated. The coating tested consisted of layers of A12O3-Mo-A12O3 AMA on various substrates. The coating was thermally cycled from 1500 to 1600F about 10,000 times, simulating conditions for three years in orbit. Results are discussed.
