Effect of hydrogen on the integrity of aluminium–oxide interface at elevated temperatures

Hydrogen gas can drive detachment of protective surface oxides from metal substrates and this process is accelerated at moderately elevated temperatures relevant to applications. Here the authors use environmental transmission electron microscopy to monitor associated void coalescence processes and...

Description
Summary:Hydrogen gas can drive detachment of protective surface oxides from metal substrates and this process is accelerated at moderately elevated temperatures relevant to applications. Here the authors use environmental transmission electron microscopy to monitor associated void coalescence processes and clarify roles that diffusion and hydrogen-vacancy complexes play.
