3. Mechanisms of hydrogen absorption by the bath

The main source of hydrogen dissolved in aluminum baths is the reaction between the metal and water, which is reduced by the latter. The reactions involved are as follows, and are shown schematically on figure 2 :

\begin{matrix} \begin{matrix} 3 [[H_{2} O]] \\ vapeur \\ dans l’atmosphère \end{matrix} & \begin{array}{l} + 2 (Al) & < {Al}_{2} O_{3} > \\ liquide solide \end{array} & \begin{matrix} + 6 ((H)) \\ dissous \\ dans Al liquide \end{matrix} \end{matrix}
