This work is devoted to studying the accumulation of hydrogen in titanium coatings to use a completely new concept of hydrogen accumulators based on a system of easily replaceable cartridges. Modern hydrogen accumulators based on magnesium powder have several problems associated with uneven heating during hydrogen desorption. Increasing the efficiency of hydrogen accumulators and the possibility of their reuse and/or repair remains a topical problem. For the analysis of the microstructure of the received titanium coatings, scanning electron microscopy (SEM) was used, the structural-phase state was studied using x-ray diffraction (XRD) analysis. The coatings were hydrogenation by gas-phase saturation at 450–550 °C. Increased film thickness reduced the storage capacity of coatings. Besides hydrogenation at 450 °C, 20 µm of titanium coatings accumulated 3.96 wt.%, while 80 µm of coatings accumulated 3.98 wt.%. The chemical composition of the coatings before and after the hydrogenation was controlled using glow-discharge optical emission spectroscopy.

气相加氢钛涂层中氢的积累与分布

这项工作致力于研究钛涂层中氢的积累，以便使用基于易于更换的滤芯系统的全新概念的储氢器。基于镁粉的现代储氢器具有与氢解吸期间加热不均匀相关的几个问题。提高储氢器的效率以及其再利用和/或维修的可能性仍然是一个热门问题。为了分析接收到的钛涂层的微观结构，使用扫描电子显微镜（SEM），并使用X射线衍射（XRD）分析研究了结构相态。涂层在450–550°C下通过气相饱和进行氢化。漆膜厚度的增加降低了涂料的储存能力。除了在450°C下氢化外，20微米的钛涂层累积3.96重量％，而80微米的涂层累积3.98重量％。使用辉光放电光发射光谱法控制氢化前后涂层的化学组成。
