What changed
East China University of Science and Technology’s “Yushi Zhiyuan” project team has developed a self-healing anti-corrosion coating aimed at deep-sea wind-power equipment.
The coating combines barrier, photoelectric and corrosion-inhibiting protection. After long-term seawater immersion tests, its protective performance reportedly remained stable, and the team has completed kilogram-scale production tests without losing core performance.
Why it matters
Corrosion is especially difficult in splash zones, where wind-power structures face repeated wetting and drying and sustained exposure to salt. Once a coating breaks, repairing equipment far offshore is difficult and expensive.
The team’s approach tries to make the coating respond to damage rather than merely cover the metal. That could matter most for equipment expected to remain in harsh marine conditions for long periods, where a small failure can become a maintenance problem.
The result is still a research milestone, not a proven commercial product. The team is working on different protection formulas for different corrosion zones, stronger repeated self-repair, weak-light performance and lower-cost production. It also plans pre-certification and long-term testing in real marine conditions before seeking its first engineering application.
