Tóm tắt:	Заглавие с экрана Nanoscale multilayer coatings (NMCs) have many advantages such as resistance to corrosion, scratches and radiation. They also have high strength and toughness, which makes them useful in industry. However, nanoscale multilayer coatings can be exposed to hydrogen, which can lead to embrittlement and changes in their structure. To better utilize these materials, it is necessary to study their structural changes after exposure to hydrogen. Hydrogen can lead to the formation of complexes with material atoms and cause defect formation. Interfaces can also be sites of hydrogen concentration. Zirconium and niobium, the nanoscale multilayer coatings used in this work, have different characteristics. Zirconium suffers from hydrogen embrittlement, while niobium can induce deformation by hydrogen accumulation. Therefore, it is necessary to investigate the structural changes in such systems after hydrogenation. The hydrogenation pressure and time are factors affecting the hydrogen concentration and distribution as well as the microstructure of the coatings. The layer-by-layer analysis of structural defects was carried out by the Doppler broadening spectroscopy (DBS) method using a variable energy positron beam Текстовый файл
