| Abstract: |
| Based on the hydrogen atoms permeating into the 6061-T6 Al alloy liner of Type Ⅲ hydrogen storage cylinder during hydrogen charging-discharging for many times, which results in the property degradation of the Al alloy liner, in this paper, research progress on the hydrogen permeation behavior and its effect on the tensile mechanical properties and the fatigue properties of the aluminum and aluminum alloys including 6061 Al was reviewed from three aspects of hydrogen permeation damage, high pressure gas hydrogen permeation and aqueous solution hydrogen permeation. The advantages and disadvantages of the high pressure gas hydrogen permeation and the aqueous solution hydrogen permeation in studying the mechanism of the hydrogen damage were also simply summarized. Finally, it was suggested that compared with the high-pressure gas hydrogen permeation, the aqueous solution hydrogen permeation method had various advantages such as high hydrogen concentration and permeating efficiency and simple process, therefore, was recommended in the research of the hydrogen induced damage and reliability evaluation of the type Ⅲ hydrogen storage cylinder. |
