Self-healing coating protects metals from corrosion

Corrosion in metals can lead to the structural fatigue or failure of bridges, pipelines, and plane fuselages. Anti-corrosion coatings help prevent this, but they become ineffective when pierced, cracked, or scratched away. Researchers at Northwestern University have now developed a self-healing coating that can patch up its imperfections in a matter of seconds.
