NON-DESTRUCTIVE SPATIAL CONTROL OF HYDROGEN ENERGY MATERIALS
Аннотация
Modern research in the field of hydrogen energy requires not only the development of new materials for hydrogen storage and transportation but also the implementation of innovative methodological approaches for their analysis. This study proposes a conceptually new approach for assessing the uniformity and stability of hydrogen materials, based on an analogy with dosimetric verification methods traditionally used in radiation therapy. Specifically, the Delta4 Phantom+ phantom model and GafChromic EBT3 radiochromic film, widely applied in tomotherapy, were adapted for the spatial and temporal visualization of hydrogen distribution both within the material volume and across cross-sections.
The concept of «hydrogen gamma-analysis» has been introduced, which includes the quantitative evaluation of discrepancies between theoretically calculated and experimentally measured parameters (hydrogen capacity, ionic conductivity, and defect density). Model experimental data are provided to demonstrate the applicability of this methodology to a range of oxide and intermetallic systems.
The use of approaches analogous to those employed with EBT3 additionally enabled the evaluation of hydrogen distribution in planar sections, the localization of degradation zones, and the analysis of changes in material properties over time. The proposed methodological framework can be utilized for modeling material degradation during cyclic loading, assessing local inhomogeneities, and optimizing the composition of hydrogen storage materials.
