| 摘 要： | 目的研究几种典型金属材料在西沙海洋飞溅区的腐蚀行为规律。方法通过外场暴露试验,分析3种钢、1种铜和3种铝合金材料暴露0.5,1,2 a后的腐蚀形貌与动力学规律。结果 3种钢的腐蚀质量损失与点蚀均较为严重,T2整个表面均匀减薄的同时,会产生大量微小的腐蚀坑,3种铝合金发生以点蚀为主的局部腐蚀,伴随有晶间腐蚀、选择性腐蚀等。结论试验条件下,3种钢中Q235耐蚀性最差,T2整体耐蚀性较好,3种铝合金中5083耐点蚀性能最差,5052略优于6063。

| 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. |
