A dilatometric study of nickel wire electrode electrochemically charged by hydrogen
Journal of Alloys and Compounds, 1996Abstract The cathodic charging of nickel with hydrogen was studied with simultaneous measurements of dimensional variations within the solubility region. Relative dimensional changes as low as 3 × 10 −6 could be detected which makes this measuring combination sensitive and powerful in studying the behavior of metal hydrogen systems, particularly in ...

Hemispherical bubbles growth on electrochemically charged aluminum with hydrogen
International Journal of Hydrogen Energy, 2007The formation of surface bubbles (blisters) in aluminum during electrochemical charging by hydrogen was studied. The experiments reveal that, in aluminum samples, a wide distribution of hydrogen bubbles on the surface (blisters) was produced during electrochemical charging.

Effects of electrochemical hydrogen charging on electrical properties of WO3 ceramics
Journal of Materials Science, 2007Tungsten trioxide (WO3) films are used extensively in eletrochromic devices [1], surface acoustic wave gas sensors [2] and photo-catalytic degradation [3]. In recent years, there has also been a growing interest in WO3-based ceramics. Due to their high dielectric constant, WO3 ceramics have been proposed for applications in ceramic capacitors [4].

Abstract Hydrogen induced cracks were introduced in an ultra-low carbon (ULC) steel by subjecting it to electrochemical hydrogen charging. The damage characteristics were investigated for three material conditions, i.e. cold deformed, recovered, and recrystallized state.

Abstract We report the electrochemical hydrogen charge/discharge properties of electrodes containing crystalline and amorphous FePO 4 as active material in KOH electrolyte. Crystalline and amorphous FePO 4 were synthesized by an alcohol-assisted precipitation method, and the powders obtained were characterized by X-ray diffraction.

Hydride dissociation and hydrogen evolution behavior of electrochemically charged pure titanium
Journal of Alloys and Compounds, 1995Abstract A commercially pure α-titanium was electrochemically charged with hydrogen in a 5% H2SO4 solution at a current density of 5 kA m−2 for 14.4 ks (4 h), and the dissociation process of the electrochemically formed hydride and the evolution behavior of hydrogen from the samples were investigated by means of high temperature X-ray diffractometry,

The influences of nanophases (titanium hydride compounds) on the formation of nanostructural titanium oxide by electrochemical treatment was investigated by XPS, GIXRD, TEM, and SEM. Nanostructural TiO2 was formed after anodization with cathodic pretreatments. The nano-TiH2 is formed by cathodic pretreatments.

Pipeline steel system always faces a challenge of hydrogen embrittlement (HE) not only due to corrosion environments but also because of cathodic protection strategy. Especially in welded joint, heterogeneous microstructures lead to the difference in intrinsic HE resistance for different subzones.
