Cryosorption of Hydrogen on Anodized Aluminum at 20 K

摘要

Hydrogen was adsorbed on anodized aluminum surfaces cooled to 20 deg K. Experiments determined the effect of various contaminants (N2, CO, CO2) which might be deposited if these panels were used in a typical rocket exhaust plume. Panels were also tested after being coated with diffusion pump oil. Several cleanup techniques were evaluated, and bakeout by heat lamps proved the most effective. Work should continue in the areas of heavy anodizing activation, structure optimization, and testing a baffle to remove rocket plume contaminants. (Author)
