| Abstract: |
| Based on the investigation of corrosion during the service of aero engines in marine environments, combined with literature review, the current application status of corrosion protection and control technology was analyzed, and future work suggestions were proposed. The corrosion protection and control of engines serving in marine environments currently lack comprehensive consideration throughout the entire life cycle, including scheme demonstration, design and development, and use and maintenance. Key technologies that restrict the solution of corrosion problems have not been breakthrough, and evaluation of corrosion performance in the engine development and production is not fully rationalized. Research and application of smart corrosion monitoring, identification, simulation technologies, et al. should be carried out to achieve early corrosion damage warning of engines in marine environments. Technical systems for testing & evaluating the adaptability of engine to corrosion environments should be built to meet the new requirements of equipment testing and identification. It is urgent to conduct research on long-life protective coatings and maintenance technology to adapt to the harsh marine atmospheric environment and requirements for the development of aviation power devices with high reliability. |
