This section presents the different mechanisms of corrosion.

2.1 General

Iron is highly sensitive to an oxygenated active medium, and its surface becomes a zone of intense ionic exchange, between one pole ( $–$ ), the anode, and one pole ( $+$ ), the cathode. We then progressively observe the "consumption" of the anode according to the following reaction:

\begin{array}{l} Fe \to Fe^{++} + 2 e^{–} \\ 1 / 2 O_{2} + H_{2} O + 2 e^{–} \to 2 {OH}^{–} \end{array}

then...
