Abstract Scope |
Charging hydrogen electrochemically into a metal is commonly carried out in hydrogen research to imitate application-relevant hydrogen update conditions. We have here investigated the use of the reverse methodology to electrochemically desorb hydrogen out from metals. Different electrolytes were investigated for this purpose, to increase the feasibility of the application for industrial applications. The results showed that hydrogen could be effectively desorbed out from the hydrogen-charged metals and mechanical properties were restored to certain levels. Using in-situ SEM-TDS (Thermal Desorption Spectroscopy) and hydrogen mapping methodologies, the reversible and irreversible trapping sites of hydrogen from electrochemical desorption were investigated in different metals and were correlated with the observed trends in the mechanical properties. |
