Hydrogen diffusion in ultrafine-grained titanium alloy with palladium

Abstract

The results of studies of hydrogen distribution in the near-surface layer after electrolytic hydrogenation in a physiological solution of plate-like samples of Ti-0.16Pd alloy with a fine-grained (FG) and ultrafine grained structure (UFG) by glow discharge optical emission spectroscopy (GD-OES) are presented. An estimate of the diffusion coefficient of hydrogen D_H for samples with FG structure give D_H ≈ 7 × 10^-17 m²/s and for samples with a UFG structure D_H ≈ 4 10^-17 m²/s. X-ray diffraction analysis showed that TiH_1.4 hydride is formed in the surface layer.
