Keywords:Tritium, Permeation, Coating, Erbium oxide, Zirconium oxide

Er2O3-ZrO2 composite coatings were fabricated by metal organic decomposition for the development of tritium permeation barrier in fusion blanket systems. Deuterium permeation through the coatings with different layer structures were examined to elucidate the relationship between layer structure and permeation behavior.
