文摘

Silver is one of the biocides of water consumed in the International Space Station. Ionic silver is depleted from potable water when in contact with stainless steel (SS). SEM and XPS analysis reveal a uniform silver deposition over the SS surface. Silver deposits in its metallic form, in line with a galvanic deposition mechanism. Evidence is provided that Cr and/ or Ni oxide builds-up on SS surfaces.
