摘要
应用反应速率分析方法，测定了钛片和表面有阳极氧化层的钛片在恒容体系和475～680℃下的吸氘反应速率常数，得到钛片和有阳极氧化层的钛片吸氘的活化能分别为112±2kJ／mol和187±3kJ／mol；钛表面氧化层越厚，表观活化能越大；实验证明氧化层具有阻氘性能。
The reaction rate for the deuterium absorption of titanium and titanium with anodic oxide layer in a constant volume system are measured in the temperature range of 475 to 680℃. The activation energy values obtained by this analysis for the absorption of titanium and titanium with anodic oxide layer are 112±2 and 187±3 kJ/mol, respectively. The thicker the oxide layer on titanium's surface is, the larger the activation energy values is. The results of experiment show that the anodic oxide layer has the prop...
