| Abstract: |
| The work aims to summarize the factors affecting the stress corrosion of high-strength steel from the aspects of alloy composition, metallographic structure, processing technology, residual stress, seawater temperature, Cl- concentration, pH and other environmental conditions and corrosion degree. Combined with the operating environment and mechanical characteristics of high-strength steel, the stress corrosion cracking mechanism of high-strength steel was briefly introduced, including hydrogen induced cracking theory, anode dissolution theory, corrosion product wedging theory, stress adsorption cracking theory, etc. Aiming at the problem of stress corrosion of high strength steel in marine environment, the protection methods of stress corrosion were discussed from the aspects of structure composition optimization, surface treatment and cathodic protection. Finally, the development direction of stress corrosion mechanism and protection was prospected. |
