| Riassunto: | Title screen In this work, hydrogen behavior in magnetron-sputtered nanolaminated coatings composed of alternating niobium and zirconium layers (Nb/Zr) is investigated. The samples were subjected to gas-phase hydrogenation at 350°C and 10 atm. X-ray structural analysis (XRD) was used to assess phase transformations, and glow-discharge optical emission spectrometry (GD-OES) was employed to study depth distribution profiles. This combined approach enabled analysis of both structural changes in the coatings and features of the hydrogen depth distribution. GD-OES profiles were interpreted with allowance for specific sputtering effects in multilayer systems. It was established that hydrogen is predominantly localized in the zirconium layers, while both the degree of retention and the spatial distribution depend on the coating architecture. The largest hydrogen uptake was observed for systems with individual layer thicknesses of 25–50 nm. Subsequent thermal treatment causes hydrogen desorption, the extent of which is likewise determined by layer thickness and periodicity. The results indicate that the hydrogen-related properties of Nb/Zr nanolaminates can be controlled via architectural parameters. The study is of interest for the design of functional multilayer materials for hydrogen-energy applications, including storage, buffering, and flow control systems Текстовый файл AM_Agreement |
