| Abstract: | Objective To study the protection measures against stress corrosion of 300M ultra-high strength steel for landing gear. Methods The mechanism of stress corrosion cracking of 300M ultra-high strength steel for landing gear was analyzed. Results According to the effects of the source of stress and the stress corrosion environment on the landing gear, optimization was conducted from aspects of the manufacturing process, the surface stress state and the surface treatment methods of the material. Conclusion The stress corrosion resistance of landing gear was improved, and the prevention measures against stress corrosion of landing gear were summarized. |
