To investigate corrosion behavior of tritium permeation barrier coatings, immersion tests in static liquid Li_15.7Pb_84.3 for 50-1500 h were performed with single Er₂O₃ layer and Er₂O₃-Fe coatings. Deuterium permeation measurements for the coating after immersion were also carried out to investigate the influence of the corrosion on tritium permeation behavior.
