Abstract The depth profiling of hydrogen and deuterium in polycrystalline and monocrystalline Nickel-base alloys (Ni-16Cr-8Fe, wt%) was performed by Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS) and Elastic Recoil Detection Analysis (ERDA) after oxidation in simulated primary medium conditions containing 9 at.% D2O. The use of deuterium isotopic tracer in ToF-SIMS has demonstrated the presence of deuterium in the oxide layer for oxidation times of 300 min and 100 h. The quantities of deuterium were determined by ERDA using a 2 MeV 4He ion beam. Finally, the penetration coefficient α was calculated, and ranged from 0.01 to 0.04.

水中氧化镍基合金中氢和氘的 ToF-SIMS 和 ERDA 研究

摘要 通过飞行时间二次离子质谱 (ToF-SIMS) 和弹性反冲检测分析 (ERDA) 对多晶和单晶镍基合金 (Ni-16Cr-8Fe, wt%) 中的氢和氘进行深度分析。在含有 9 at.% D2O 的模拟主要介质条件下氧化。在 ToF-SIMS 中使用氘同位素示踪剂已证明氧化层中存在氘，氧化时间为 300 分钟和 100 小时。使用 2 MeV 4He 离子束通过 ERDA 测定氘的量。最后，计算渗透系数α，其范围为0.01至0.04。
