A study of corrosion damage and material characterization of two historic military tanks, the Sherman and Centaur is reported. Experiments were conducted to analyse surface corrosion and corrosion propagation from surface to sub-surface. Significant surface corrosion was found, and this phenomenon was further facilitated by delamination failure mechanisms. Corrosion depth for the Sherman was approximately 110 μm, where sulphide inclusions were detected in the sub-surface analysis. The Centaur's analysis showed corrosion pits at 100 μm depth. These pits possess random geometrical configurations with evidence of sulphur, sodium, and calcium.
