The new nano-composite coating technology developed by the Institute of Metal Research of the Chinese Academy of Sciences has been successfully tested on large-scale transport aircraft, significantly improving the anti-corrosion performance and overhaul quality of the aircraft. Up to now, of the three aircraft using the technology, two have been used for four years and four months after major repairs, and the other one has been used for two years and one month after major repairs. The anti-corrosion coating on the three airplanes was in good condition overall and there was no aging failure. It was obviously better than the protective effect of the body coating before overhaul. It is reported that the technology is intended to be applied in various types of aircraft.
Due to environmental and other factors, the coating of aircraft originally coated with imported high-grade paints appeared to be powdered and peeled in less than two years, and localized corrosion of the aircraft skin not only reduced the safety of the aircraft, but also increased the Maintenance time greatly reduces the use efficiency.
