The influence of concretion on the long-term corrosion rate of steel shipwrecks in the Belgian North Sea

Some three hundred mainly steel shipwrecks from both World Wars lie buried at shallow depths along the Belgian North Sea coast. They were examined recently to estimate corrosion rates over periods in excess of 100 years. The rate was estimated by comparing the measured in-situ steel plate thicknesses with archived ship information. The estimates show distinctly lower long-term corrosion rate compared to that predicted by the Melchers (Modeling of marine immersion corrosion for mild and low alloy steels – part 1: phenomenological model. Corrosion. 2003;59(4):319–334) corrosion model, when param... Mehr ...
