Cover: Optical microscopy of anodes self‐corrosion after 139 days in the deep sea at a depth of 1420 m: (a) Al‐Zn‐In‐Mg‐Ti‐Ga‐Mn, corrosion pits with two kinds of distinct surface morphologies: (i) deep pits (pit 1: typically 300 μm deep) and (ii) broad/shallow pits with rough surface features (pit 2: typically 75 μm deep). (b) Al‐Zn‐In‐Si, only large corrosion pit features and the diameter is about 2.5 mm.
