Ser. : Plasma physics. – 2017. – No. 1 (107). – P. 123-125.https://repository.kpi.kharkov.ua/handle/KhPI-Press/53856Structure, substructure and stress parameters both on the surface and distributed by depth in the tungsten/steel coatings exposed to high energy hydrogen plasma fluxes were studied by X-ray diffraction methods. The hydrogen plasma exposure results in the following recrystallization processes in the thin surface layer of the coating: appearing the texture axis normal to the surface; increasing the coherence length from 60 nm in the initial state to 80 nm after the plasma exposure; completely annealed micro-strains; and dislocation density lowered twice in the exposed surface layer all these facts confirm the thermal character of the hydrogen plasma influence.entungsten coatingsplasma flowshydrogen plasmarecrystallization processesX-raysStructure evolution of tungsten coatings exposed to plasma flows under ITER ELM relevant conditionsArticle
