摘要：热脱附光谱（TDS）最初是一种表面表征技术，但已成为一种广泛使用的方法来研究金属材料中的氢捕获现象。本章将详细审查这一技术。因此，将讨论完整的测量程序。一个主要的问题将是氢引入到材料中，这次审查将提供不同的充氢程序的概述。充电后，由于氢的高迁移率，可扩散氢将立即开始从充电样品中逃逸，如本章所示。本章的主要部分将致力于TDS测量本身，重点将放在所获得的数据的处理和建模上。最后，将注意到电化学渗透技术，它可以与TDS结合使用，并提供氢和金属之间的相互作用的补充信息。
Abstract: Thermal desorption spectroscopy (TDS) was originally a surface characterization technique but has become a widely used method to investigate the phenomenon of hydrogen trapping in metallic materials. Within the present chapter, this technique will be reviewed in detail. Therefore, the complete measurement procedure will be addressed. A primary concern will be the introduction of hydrogen into the material; this review will provide an overview of the different hydrogen charging procedures. After charging, the diffusible hydrogen will immediately start to escape from the charged sample due to the high hydrogen mobility, as illustrated in this chapter. The major part of this chapter will be dedicated to the TDS measurement itself where focus will be on the treatment and modeling of the obtained data. Finally, attention will be given to the electrochemical permeation technique which can be used in combination with TDS and provides supplementary information of the interaction between hydrogen and metal.
