A Russian invention protects airplanes from rust and corrosion while reducing costs.

A team of Russian scientists at the Institute of General Research of Russia for Aviation Materials, affiliated with the National Research Center "Kurchatov Institute," has announced the invention of a new aircraft coating known for its high resistance to corrosion and rust, significantly reducing the need for aircraft repairs and maintenance. This new coating contains advanced components including fluoropolyurethane enamel and weather-resistant varnish, making it suitable for use on various surfaces used in aircraft manufacturing, whether metal, polymers, or composite materials. According to the scientific center's press office, the new coating reduces the need for repairs by at least 40% compared to similar foreign coatings and contributes to reducing the coating cycle time by over 50%. Additionally, it is significantly lightweight, weighing 35% less than other alternatives. One of the key features of this innovation is its "self-repair" capability; the coating contains microcapsules loaded with therapeutic materials that automatically burst upon scratches or damage, releasing their contents to self-repair the damage without the need for external intervention. The coating is highly resistant to corrosion and rust, enhancing the structural resistance of aircraft to environmental factors like moisture and salinity, thereby extending the aircraft's lifespan and reducing maintenance costs. The coating is applied using advanced manufacturing techniques including magnetron sputtering and spark alloys, ensuring uniform distribution on the aircraft's surface, enhancing its efficiency and effectiveness. This innovation is expected to bring a qualitative shift in the aviation industry, directly impacting the reduction of operational costs for airlines, increasing aircraft lifespan, and improving aviation safety, benefiting both companies and users alike.
