Study of Hydrogen Migration in Titanium Using a Vortex Electromagnetic Field and Accelerated Electrons in Subthreshold Values

The migration of hydrogen in a homogeneously hydrogen-saturated commercial titanium VT1-0 has been studied using a high-frequency electromagnetic field and an accelerated electron beam. The use of a high-frequency 50–1000 kHz electromagnetic field, which generates eddy currents in the material, made it possible to observe the process of hydrogen migration near the surface and in the depth of the sample. To accelerate the migration of hydrogen in the volume of the sample electron irradiation with an energy of 30–45 keV was used. The migration process was studied in an inhomogeneously hydrogen-saturated commercial titanium sample with a titanium nitride film deposited on its surface by magnetron sputtering. VT1-0 flat samples were saturated with hydrogen using the Sieverts method. The diffusion coefficient of hydrogen in titanium was determined from the change in the magnitude of the signal from the eddy current sensor along the depth of the sample and along the sample, as hydrogen migrated in the sample. The values of the diffusion coefficients of hydrogen along the surface and in the depth of the sample under equilibrium conditions and under stimulation by an accelerated electron beam were obtained.
