New nanotech coating heals itself to stop metal rust

Researchers at the Australian Institute for Bioengineering and Nanotechnology have created a new self-repairing coating designed to stop rust and protect metal surfaces for a much longer time. Rust causes massive damage to industrial equipment, bridges, and vehicles every year by eating away at steel and iron structures. This advanced coating uses nanotechnology to detect damage on its own and fix the broken areas before rust can form and spread. The protective layer can heal tiny cracks and scratches automatically when they happen. This cuts down the high cost of repairs and regular maintenance for factories and builders. The team built this solution to make metal parts last longer in tough weather and harsh work sites.
