| Abstract: |
| This paper reviewed the research progress of corrosion and protection technology for the reduction gearbox of the hovercraft in the marine atmosphere and seawater sputtering environment. The corrosion characteristics and main corrosion types of the reduction gear box of the hovercraft under long-term high temperature, high humidity, high salt spray and seawater sputtering environment were introduced, and the research progress of the corrosion protection technology of the parts of the reduction gear box with different materials was summarized. Finally, it was proposed that the corrosion protection of the reduction gear box of the hovercraft in the marine environment should start from the aspects of structural design, material selection, processing and manufacturing, transportation and storage, maintenance, etc. On the basis of making full use of the existing surface treatment technology, combination of anodic oxidation, micro-arc oxidation, electroplating, paint coating and other technologies should be strengthened. The corrosion monitoring technology should be focused on to effectively warn the failure of the protective layer, and long-term effective and green surface treatment technology and coating technology in the marine environment should be vigorously developed. System engineering was used to improve the environmental adaptability of metal materials in the marine environment, thereby improving the reliability and safety of components such as reduction gear boxes. |
