Key Takeaways
Localized pitting corrosion in aluminum components can cause sudden failure.
Overall corrosion rates can be low even when pitting occurs.
Steam coating is a water-vapor-based route to protective boehmite films.
Steam coating simultaneously changes film thickness, surface morphology, crystallinity, and substrate defects.
Overview
Localized pitting corrosion poses a significant concern for aluminum components due to its potential to cause sudden structural failure, even when the overall corrosion rates remain low. A method for mitigating this phenomenon involves the application of protective films, such as boehmite films, through a process known as steam coating. This water-vapor-based deposition technique concurrently influences several material properties. Specifically, steam coating simultaneously modifies the film thickness, the surface morphology of the coated material, the crystallinity of the protective film, and the nature of substrate defects present.
