This paper deals with the formation of a deuterium barrier on SiC/SiC composites proposed as low activation structural materials for the first wall of a fusion reactor. An Al-Si (12 %) eutectic has been coated on SiC/SiC by a plasma spraying process and subsequently heat treated to maximise the interfacial bond strength. Permeation measurements were performed in the temperature range 300-750 K using deuterium at pressure in the range 0.5-150 KPa.
