| Abstract: |
| Objective To investigate the corrosion behavior and rules of typical metal materials in Xisha marine splash zone. Methods Field exposure test was carried out on 3 kinds of steels, 1 kind of copper and 3 kinds of aluminium alloy materials for 0.5 a, 1 a and 2 a to analyze their corrosion morphology and kinetics rule. Results The corrosion weight loss and pitting phenomenon for 3 kinds of steels were severe; tiny corrosion pits were formed on entire surface of T2 during its evenly thinning process; localized corrosion which was mainly composed of pits occurred on three kinds of aluminium alloy, accompanied by intergranular corrosion, selective corrosion, et al. Conclusion Under the test conditions, the corrosion resistance of Q235 is the worst among 3 kinds of steels; T2 has a good overall corrosion resistance; pitting resistance of 5083 is the worst, while 5052 is slightly better than 6063. |
