Briefings

A 2026 study by AI researchers indicates that coating thickness significantly alters the relationship between surface roughness and pitting resistance in aluminum components. The study highlights that steam-based coating processes simultaneously modify film thickness, surface morphology, crystallinity, and substrate defects, potentially causing localized pitting failure despite low overall corrosion rates.

Key points

• Localized pitting corrosion can cause sudden failure in aluminum components even when overall corrosion rates remain low.
• Steam coating processes simultaneously change film thickness, surface morphology, crystallinity, and substrate defects during the protective boehmite film formation.

Context and limitations

The evidence is limited to a single study from October 2026 and does not include long-term durability data, comparative analysis with other coating methods, or field test results.
