Abstract

Graphical abstract: The reaction mechanism for in situ synthesizing TiH{sub 2} layer on titanium foil by a gaseous hydrogen free acid-hydrothermal methodology. - Highlights: • A dense TiH{sub 2} layer is synthesized by a hydrogen free acid-hydrothermal method. • Hydrogen in a TiH{sub 2} layer synthesized can release at low temperature. • During the dehydrogenation process, there is no any intermediate phase forming. • We report a method of low-cost, low-risk and convenience toward productive TiH{sub 2}. - Abstract: A novel strategy for synthesis of TiH{sub 2} layer on surface of metallic titanium by using an acid-hydrothermal method was proposed. During the synthesis process, no any elemental hydrogen was involved. X-ray powder diffraction, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy and scanning electron microscopy results confirmed that a TiH{sub 2} layer of 20 μm thickness on a Ti foil surface can be formed in situ by an interface reaction of metallic titanium with sulfuric acid solution, hydrochloric acid, or phosphoric acid, which is a hydrogen self-storage process. By tuning reaction parameters, for example, concentration of acid, composition and morphology of TiH{sub 2}-Ti hybrid materials can be adjusted. The TiH{sub 2} layer on a metallic titanium surface can be decompounded completely heatedmore »« less

Understanding the TiH_(2-x)/TiO_y System at Elevated Temperature: A Literature Review

Technical Report Beste, Ariana; Bufford, Daniel

Titanium hydride of varying TiH stoichiometry is used in pyrotechnic compositions. In order to yield consistent performance, manufacturing processes must be developed to ensure precise and reproducible material properties, including composition and morphology. Legacy synthesis protocols are not comprehensive nor are the required apparatuses still available. To guide the development of novel production procedures, this report reviews literature on relevant chemical reactions and diffusion events occurring at elevated temperature in the TiH_(2-x)/TiO_y system. Titanium hydride exposed to air spontaneously forms a passivating oxide layer. Upon heating, significant hydrogen release, which is accompanied by changes to the surface oxide layer, ismore »« less

Effect of sodium sulfide on hydrogen absorption of Ti-6% Al-4% V alloy

Journal Article Wu, T; Liu, C; Wu, J - Corrosion

The hydrogenation inhibitive effect of sodium sulfide on Ti-6% Al-4% V alloy (UNS R56400) in aqueous sulfuric acid solution (H{sub 2}SO{sub 4[aq]}) was investigated qualitatively and quantitatively using optical microscopy, x-ray diffraction (XRD), and glow-discharge spectrometry (GDS). Introduction of Na{sub 2}S into the electrolyte resulted in an obvious inhibitive effect of hydrogen absorption on as-received (covered with a thin thermal oxide film < 0.5 {micro}m) and abraded specimens (free of thermal oxide film) irrespective of applied current density and operating period. The contrary effect of Na{sub 2}S on Ti-6% Al-4% V alloy vs ferrous alloys could have resulted from themore »« less

Synthesis and characterization of a novel layered sodium titanium silicate Na{sub 2}TiSi{sub 2}O{sub 7}{center_dot}2H{sub 2}O

Journal Article Clearfield, A; Bortun, A; Bortun, L; ... - Solvent Extraction and Ion Exchange

A novel layered sodium titanium silicate Na{sub 2}TiSi{sub 2}O{sub 7}{center_dot}2H{sub 2}O has been synthesized by the reaction of a titanium-hydrogen peroxide complex and silicic acid in alkaline media under mild hydrothermal conditions (200{degree}C). The product was characterized by elemental analysis, TGA, FT-IR, MAS {sup 29}Si and {sup 23}Na NMR and X-ray spectroscopy. The intercalation reaction of n-alkylamines from the gaseous phase and the ion exchange behavior of Na{sub 2}TiSi{sub 2}O{sub 7}{center_dot}2H{sub 2}O towards alkali, alkaline earth and some transition metal ions in model individual and complex solutions were studied. It was found that the layered sodium titanium silicate contains acidicmore »« less

Influence of TiH{sub 2} on Interfacial Reaction Features Between Cubic Boron Nitride and Cu-Sn-Ti Active Filler Metals

Journal Article Fan, Yonggang; Fan, Junxiang; Wang, Cong - Metallurgical and Materials Transactions. B, Process Metallurgy and Materials Processing Science

Cubic boron nitride (CBN) grains are brazed by Cu-Sn-Ti filler metal in vacuum at 1223 K. Wetting behaviors, reaction layer features, and elemental distribution characteristics have been systematically investigated through scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD). The results show that when the TiH{sub 2} content is 5 wt pct, virtually no sharp-edged, partially coated, and uncoated CBN grains can be observed, indicating that adequate wetting could be achieved. Moreover, a continuous reaction layer with uniform thickness (1.30 μm) consisting of TiN, TiB{sub 2}, and TiB is obtained, which indicates that large numbers of TiN, TiB{sub 2}, andmore »« less

Thermal annealing synthesis of titanium-dioxide nanowire-nanoparticle hetero-structures

Journal Article Yu, Choongho; Park, Jongbok - Journal of Solid State Chemistry

Crystalline TiO{sub 2} nanowire-nanoparticle hetero-structures were successfully synthesized from titanium foils by using a simple thermal annealing method with the aid of CuCl{sub 2} at the atmospheric pressure. Nanowires were grown from Ti foils by simply annealing Ti foils at 850 {sup o}C. Then, TiCl{sub 4} was delivered to TiO{sub 2} nanowires so as to precipitate TiO{sub 2} nanoparticles on nanowire surfaces. At 750 {sup o}C reaction temperature, nanoparticles of tens of nanometers in diameter were well distributed on pre-grown nanowire forests. Nanoparticles were likely to be precipitated by TiCl{sub 4} decomposition or oxidation and that require high temperatures abovemore »« less
