摘　　要：通过优化钛的吸氢工艺,成功制备了不同氢氘含量的氢/氘化钛样品;结合XRD分析,给出了钛吸氢前后的晶体结构变化。利用热脱附谱(TDS)技术,通过标准漏孔标定质谱仪的离子流信号强度,实现了钛中氢同位素脱附量的定量测定;TDS法测量结果与压力-体积法测量值之间的绝对误差小于6%。研究结果可为氢能、核能及核技术领域材料中氢同位素含量的准确测量提供有益参考。Titanium hydrogenated/deuteride samples with different hydrogen and deuterium contents were successfully prepared by optimizing the hydrogen absorption process of titanium.Combined with XRD analysis,the crystal structure changes of titanium before and after hydrogen absorption were given.Using thermal desorption spectroscopy(TDS)technology developed by our research group,the ion current signal intensity of the mass spectrometer was calibrated by a standard leakage,and the quantitative analysis of the amount of hydrogen isotope desorption in titanium was realized.The absolute error between the TDS measurement result and the pressure-volume method measurement value is less than 6%.The total contents of hydrogen and deuterium desorbed in the sample were calculated.The results provide a useful reference for the accurate measurement of hydrogen isotope content in materials in the field of hydrogen energy,nuclear energy and nuclear technology.
