【摘要】：氢能作为重要的二次能源,因其具有来源多样、储运便捷、清洁环保、利用高效等优点受到了各国的青睐。高压储氢容器是氢能的重要储输设备之一,其材料氢脆问题是氢能及其相关技术发展中的瓶颈,并逐渐发展为金属材料科学领域中一个非常重要且活跃的研究方向。热脱附谱(TDS)作为一种研究材料中氢陷阱特性的重要方法,得到了国内外学者的广泛使用。本文首先在综合介绍TDS装置及其测试原理的基础上,讨论了升温热脱过程中可能发生的氢陷阱变化对TDS结果及分析的影响。然后通过对TDS试样预处理技术发展水平及各技术利弊的分析,讨论了充氢技术和参数的选择以及充放氢过程对TDS试验结果的影响。最后,基于TDS数据后处理的现有理论及研究进展,讨论了TDS 3种拟合模型的适用性以及在其处理多陷阱曲线重合问题时反褶积过程的复杂性。
[Abstract]:As an important secondary energy, hydrogen energy is favored by many countries because of its advantages of diverse sources, convenient storage and transportation, clean and environmental protection, high efficiency and so on. High pressure hydrogen storage vessel is one of the important storage and transportation equipment of hydrogen energy. The hydrogen embrittlement of its materials is the bottleneck in the development of hydrogen energy and its related technology, and has gradually developed into a very important and active research direction in the field of metal material science. Thermal desorption spectroscopy (TDS), as an important method to study hydrogen trap characteristics in materials, has been widely used by scholars at home and abroad. On the basis of a comprehensive introduction of the TDS device and its testing principle, this paper discusses the influence of the possible hydrogen trap changes in the thermal desorption process on the TDS results and analysis. Then, through the analysis of the development level of TDS sample pretreatment technology and the advantages and disadvantages of each technology, the selection of hydrogen charging technology and parameters and the influence of hydrogen charging and releasing process on TDS test results are discussed. Finally, based on the existing theory and research progress of post-processing of TDS data, the applicability of three fitting models of TDS and the complexity of deconvolution process in dealing with the problem of multi-trap curve coincidence are discussed.
