Correction to “The Use of Hydrogen in Monitoring the Anoxic Corrosion of Copper”

N. Senior, T. Martino, P. G. Keech, W. Jeffrey Binns, N. Diomidis, C. Lilja, Mater. Corros. 2023, 1–11. https://doi.org/10.1002/maco.202313769. Thermal desorption analyses were used to calculate the activation energy of hydrogen outgassing from electrodeposited copper. This was then extrapolated to 75°C, the test temperature of several anoxic aqueous corrosion cells. The intention was to investigate the source of the hydrogen recorded from the cells; either from corrosion, through outgassing of hydrogen initially present in the copper, or a combination of both. A mathematical error was made when deriving the ‘H2 model’ line, resulting in a significantly elongated hydrogen outgassing curve. Correction of this error demonstrates that hydrogen outgassing at 75°C should be completed within a matter of weeks. This strengthens the argument that the hydrogen recorded over the 2-year period was primarily due to surface (not bulk) corrosion, and not hydrogen outgassing. The corrected Figures 6 and 7 are shown below. We apologize for this error.
