Additionally, the hydrogen absorption and desorption capacities of the alloys significantly increase with rising... the activation and hydriding properties. ZALUSKA et al[12] reported that a milled mixture of Mg2NiH4 and MgH2 shows the excellent absorption- desorption kinetics at 220–240 °C and a maximum hydrogen......

indicate that hydrogen permeation can be negligible if RH is less than 70%. With RH rising, the permeation curves increase gradually. The hydrogen absorption is accelerated by the cathodic protection of scratched steel surface afforded by zinc coating, and hydrogen permeation flux decreases with the exposed area of steel substrate increasing. Hydrogen absorption and permeation reduce the elongation......
Kinetics of Hydrogen Absorption in MmNi3.55Co0.75Mn0.4Al0.3 Alloy林勤,于振涛,叶文,刘人敏摘 要:KineticsofHydrogenAbsorptioninMmNi3.55Co0.75Mn0.4Al0.3AlloyLinQin(林勤),YuZhentao(于振涛),YeWen(叶文)(UniversityofSciencea...关键词:......
that can effectively increase the diffusion passageway for hydrogen atoms[23]. The hydrogen absorption and desorption curves of Mg2FeH6-based complex at different temperatures are shown in Fig.2. Fig.2(a) shows that the as-synthesized Mg2FeH6- based complex possesses good hydrogen absorption performance. Only 85 s is needed for the accomplish- ment of 90% of hydrogen absorption at 623 K under 4.0......
