dc.description.abstractThe reliance on non-permanent coatings in Condensing Heat Exchanger (CHX) designs is a significant technical issue to be solved before long-duration spaceflight can occur. Therefore, high reliability CHXs have been identified by the Evolvable Mars Campaign (EMC) as critical technologies needed to move beyond low earth orbit. In continued pursuit of Laser Processed Condensing Heat Exchanger (LP-CHX) development, a sub-scale LP-CHX coupon was designed and constructed. For construction of this coupon, numerous manufacturing methods were developed. These include development of unique laser processing methods of silver finned surfaces of various thicknesses, laser welding of silver, and unique brazing operations. Additionally, microbial growth testing and long duration condensing is reported in this paper. These studies conclude that silver laser processed surfaces significantly reduce microbial growth and increase the number silver ions found in condensate water.en_US
