目的 研究5083铝合金在淡海水交替自然环境下的耐蚀性能。方法 参照GB/T 5776,分别在淡海水交替、海水及淡水自然环境中开展5083铝合金2年的耐浸泡试验。采集每周期试验样品的腐蚀数据,并进行5083铝在三种自然水环境下的耐蚀性能比对。采用腐蚀电位、交流阻抗等电化学方法,对其耐蚀性能进行评价。结果 5083铝在淡海水交替自然环境下腐蚀严重,腐蚀速率是海水环境下的5.3倍,是淡水环境下的15.8倍。点蚀密度最大,平均点蚀深度是海水环境下的2.6倍,是淡水环境下的1.7倍。结论 5083铝在淡海水交替自然环境下的耐蚀性差,并从电化学试验结果上得到很好的验证。 |

Objective To study the corrosion resisting property of 5083 aluminum in freshwater and seawater alternate circumstance. Methods The 5083 aluminum alloy was tested in freshwater, seawater and freshwater-seawater alternate circumstances according to GB/T 5776. The corrosion data of test specimen in each period were collected to compare the corrosion resisting property of 5083 aluminum in three different natural water circumstances. Results 5083 aluminum suffered from serious corrosions in freshwater and seawater alternate circumstance. Its corrosion rate was 5.3 times of that in seawater and 15.8 times of that in freshwater. Its depth of pitting was 2.6 times of that in seawater and 1.7 times of that in freshwater. Conclusion The corrosion resistance of 5083 aluminum is poor in freshwater-seawater alternate circumstance. It is well verified by the result of the electrochemical test. |
