| Abstract: |
| Objective To study corrosion behaviors of AH36 steel in different seawater zones in Xisha. Methods The test was made by corrosion weight loss, morphology and product composition analysis after exposure in different seawater zones in Xisha. Results The power function was observed between the corrosion weight loss and exposure time in different zones, and the corrosion rate of the samples in splash zone was the highest. Slight general corrosion occurred at atmospheric zone sample, while obvious corrosion pits were observed on splash zone sample surface. Non-uniform comprehensive corrosion occurred in the submerged zone. The stable α - FeO (OH) and iron oxides were the main corrosion products in different zones, which were higher in splash zone than in atmospheric zone. Besides, calcium and magnesium deposits were also detected in corrosion products of samples in the submerged zone. Conclusion The corrosion rate of AH36 steel in Xisha sea area is fast, with the most serious corrosion of samples in the splash zone. The rate of corrosion products formation and conversion is fast, and the corrosion tends to be stable. |
