Исследование и моделирование термостимулированного выделения водорода из Ti, Zr Pd

Abstract

Thermo-stimulated hydrogen release (TSHR) at linear heating (1 °C s-1) from plane-parallel plates of Ti, Zr, Pd metals andalloys with various thicknesses (0.05-1 mm) preliminarily saturated with hydrogen by electrolytically method were studied. The diffusion and desorption hydrogen release models from flat metal samples in vacuum under linear heating are developed. At the same time, diffusion and thermo-desorption processes were taken into account in order to select optimal conditions and experimental methods. Modeling of TSHR spectra was performed using the MATLAB application package. Bysimulation with using both developed models and experimental TSHR spectra, the activation energies of desorption, diffusion, and hydrides decomposition as well as the pre-exponential factors in the equations are determined.
