研究了３１６Ｌ不锈钢表面镀ＴｉＣ和ＴｉＮ＋ＴｉＣ复合涂层材料的抗氚渗透层在聚变环境中的稳定性。研究结果表明，ＴｉＣ和ＴｉＮ＋ＴｉＣ复合涂层材料经化学热处理后在其表面层生成的抗氚渗透层能抗Ｈ＋离子辐照，能抗很大的温度梯度和热循环，经长时间实验证明这些涂层材料的抗氚渗透层性能稳定 The stability of tritium permeation layer on 316L stainless steel with TiC and TiN + TiC composite coatings was studied in a fusion environment. The results show that TiC and TiN + TiC composite coating material after chemical heat treatment in its surface layer of anti-tritium penetration layer can resist H + ion irradiation, resistant to large temperature gradient and thermal cycling, after a long period of experiments show that these coatings Tritium permeation layer of the material layer of stable performance
