【Abstract】 The stability of tritium permeation prevention barrier of 316L stainless steel with coating TiC and TiN+TiC under the conditions of very large thermal gradient, thermal cycling and plasma irradition is researched. The research includes two aspects:one is the study on the stability resisting H + plasma irradiation; another is on the ability of two coating materials when they are used in long term under the condition of very large thermal gradient and cycling. Our results show that TiC and TiN+TiC composite coating materials, after chemical heat treatment and forming tritium permeation prevention barrier, can resist H + ion irradiation, and also can resist very large thermal gradient and thermal cycling. Our long time experiments show that tritium permeation prevention barrier of those coating materials is stable when they are used in long term.更多还原
