| 中文摘要: |
| 介绍了电偶腐蚀的原理，以飞机结构上容易出现的三种电偶腐蚀(碳纤维增强环氧复合材料-铝合金、钛合金-铝合金、铝合金-不锈钢)为例，对目前关于这三种电偶腐蚀的研究进行了综述，分析了电偶腐蚀的环境影响因素，综述了耦合材料的失效特点和形式，探讨了利用阻隔、涂层和缓蚀剂等手段减缓和防止电偶的防护措施，指出利用微区测试技术、联合多种研究手段和复合环境因素在研究电偶腐蚀方面的重要性。在多因素条件下，设计模拟耦合件的试验，有利于模拟实际工况的特征。 |
| 英文摘要: |
| This paper introduced the mechanism of galvanic corrosion. The study on three typical types of galvanic corrosion prone to happen in aircraft structure (carbon fiber reinforced epoxy composite-aluminium alloy, titanium alloy-aluminium alloy, aluminium alloy-stainless steel) was reviewed. The influence of environmental factors on galvanic corrosion was analyzed and the failure characteristics and behaviors of coupling materials were given. The protective measures for mitigation of galvanic corrosion, such as separation, coatings and inhibitors were reviewed. The use of micro-zone techniques, the combination of multi-methods and the consideration of environmental factors are important to research galvanic corrosion. Under multi-factors, the design of simulated galvanic components is beneficial to simulate the actual working conditions. |
