摘要
在两种不同海域的海洋环境下对7B04铝合金铆接结构试验件进行自然曝晒,通过对试验件一年后腐蚀情况的对比分析,研究了这两种海洋服役环境对7B04铝合金的腐蚀影响。结果表明:两种海域的海洋环境对7B04铝合金铆接结构试验件都产生了明显的腐蚀行为,疲劳性能均有不同程度的下降,涂层对海洋环境能够起到较好的防护作用;同时两种海洋环境对7B04铝合金腐蚀行为的影响也表现出明显的差异性,必须对更严酷的服役环境做好针对性的腐蚀防护工作。
7B04 aluminum alloy riveted structure specimens were exposured in two different marine environments for one year.The corrosion of the specimens was comparatively analyzed,and the effect of the two service environments on the corrosion behavior of 7B04 aluminum alloy was studied.The results show that the corrosion of 7B04 aluminum alloy riveted structure specimens has occurred obviously in the two marine environments,the fatigue performance of specimens has been reduced with varying degree.But coatings can protect the aluminum alloy away from destruction in marine environment.The effect of the two marine environments on the corrosion behavior of 7B04 aluminum alloy also shows obvious difference,the corrosion protection must be done well in service environment.
