Paragraph starter
Research by Niu et al. (2023) demonstrated through simulation that pre-damage to coatings on aluminum-based skins significantly accelerates localized corrosion in riveted zones, leading to a measurable increase in electrode deposits (0.16 μm) over 30 days. This highlights the critical role of coating integrity in maintaining the long-term durability of riveted aluminum structures.
