... sulfide or chloride ions under conditions in which repassivation is hindered. Normally, it is protected by a passive oxide layer. However, chloride ions have the power to penetrate the oxide film, causing local breakdown of passivity and the formation of an anodic site. Repassivation occurs...

... corrosion reactions. When the materials are subjected to wear, the passive film can be damaged, leading to increased corrosion. Although repassivation could repair the film, continued wear can suppress such self-repairing. Wear-caused plastic deformation makes materials more anodic. Wear removes material...

... irregularities. Additionally, the repassivation of the removed oxide layer will be inhibited in the presence of aggressive environments, such as oxygen depleted areas existing in the shielded areas on a metallic surface (e.g., beneath screw heads holding a plate), and the intense local attack by corrosion...

... precipitates on the top of the pit, restricting the entry of solution and oxygen into the pit and, as consequence, the repassivation of the protective oxide film. Movement of metal ions or H+ ions from the bottom of the pit is restricted, and, as a result, the pH of the bottom of the pit is lowered...

... cracks. Liquid–metal globules rather than films are present when “de-wetting” occurs after fracture owing to diffusion of oxygen through liquid–metal films and repassivation of the fracture surface. The presence and nature of deposits can sometimes be obvious from their colour during visual examination...

... the metal. Between these two extremes there exists a range where the fresh metal at the crack tip is attacked, but the crack walls are passivated. The crack tip repassivates, but the passive layer eventually cracks and the fresh surface is attacked by anodic dissolution, which then repassivates again...
