Abstract
Experiments to simulate the corrosion of a mild steel (designated A3) in the open sea have been conducted to explain observed differences between the behaviour of suspended specimens that were electrically connected together on the one hand and unconnected on the other. Reasons for differences between the corrosion behaviour of individually suspended specimens in the laboratory and that of steel in a marine service environment have also been investigated. The effect on corrosion of the ratio of water depth in the tidal zone to that in the immersion zone has also been studied.
