Abstract : Oxide films and salt films form on metal surfaces during anodic dissolution. In high chloride concentration environments the oxide films break down and salt films form. Our overall goal is to ascertain the relationships between pitting and crack initiation, the formation and breakdown of salt films (including oxides) and mechanical stress for aluminum and titanium alloys in aggressive corrosion environments. This report presents results of some very preliminary experiments on aluminum alloys and titanium during anodic dissolution in chloride media. With more extensive studies, we seek to determine if nonlinear dynamic techniques can provide further information regarding the relationship between the fluctuations and oscillations observed during anodic metal dissolution and localized corrosion phenomena.
