| 摘要: |
| 按照爆炸复合材料的应用条件，将铝-铝-钢投放在青岛、舟山和厦门3个海域的潮差和飞溅区，暴露1a后研究了材料的腐蚀和力学性能。复合材料的腐蚀为电偶腐蚀，在铝-钢之间形成腐蚀沟槽。但是，对复合材料的力学性能影响不大。 |

| The corrosion of aluminium alloys-steel joints in different sea areas |

| Abstract: |
| Based on the using conditions of aluminium-steel joints, we exposed such samples in splash zone, ebb and flow zones in Qingdao, Zhoushan and Xiamen areas. After one year，s exposure, we studied their corrosions and mechanical performances. The corrosion of aluminium-steel joints is so-called double-metals corrosion. A deep channel was formed in the Al side of the interface. In the other hand, one year’s exposure has little done with their mechanical performances. |
| Key words: splash zone ebb and flow zone metal joint corrosion |
