Cracks

Engineers have developed a new coating strategy for metal that self-heals within seconds when scratched, scraped, or cracked. The novel material could prevent these tiny defects from turning into localized corrosion, which can cause significant structures to fail. It’s hard to believe that a tiny crack could take down a gigantic metal structure. But sometimes bridges collapse, pipelines rupture, and fuselages detach from airplanes due to hard-to-detect corrosion in tiny cracks, scratches, and dents. Localized corrosion is extremely dangerous. It is hard to prevent, hard to predict, and hard to detect, but it can lead to catastrophic failure  Engineering team […]
