Analysis of the Influence of the Cathodic Polarization Value on the Amount of Hydrogen Sorption of Al-Sm with the Alloy of Electrochemical Measurements

The effect of cathodic polarization on the rate of hydrogen sorption from an aqueous organic electrolyte on an Al-Sm alloy using the potentiostatic and potentiodynamic methods were studied. The obtained data allowed us to calculate the diffusion-kinetic characteristics of this process, such as the interstitial constant, diffusion constant $C_{\text{Н}}\!\!\sqrt{D}$, constant current iconst, diffusion coefficient D and adsorption of hydrogen atoms G. The number of nuclei decreases, but their mass and radius increase in the potential range from –2.0 V to –2.4 V.
