Certainly, inhibitors are widely used to reduce corrosion rates of materials in many corrosive environments. However, when the substrate suffers from aggressive corrosion, inhibition still neither efficient nor cost-effective for the substrate performance. In this study, we test a new green biopolymer (diazonium grafted biosurfactant, noted R11) as a repairer of damage that happens to a 3-years-old AA-5083 bar immersed into Dead Seawater. Mechanism reparation has been detailed. Electrochemical techniques, X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM), were used to study, analyze and confirm the effect of reparation of AA-5083 alloy using the R11 compound. The reparation efficiency reached 96%.

当然，在许多腐蚀性环境中，抑制剂被广泛用于降低材料的腐蚀速率。然而，当基材遭受侵蚀性腐蚀时，抑制对于基材性能仍然既不有效也不经济。在这项研究中，我们测试了一种新的绿色生物聚合物（重氮接枝的生物表面活性剂，记为R11）作为损坏的修复剂，这种浸渍剂是浸入死海水中3年之久的AA-5083压条的情况。机制赔偿已经详细说明。使用电化学技术，X射线光电子能谱（XPS）和扫描电子显微镜（SEM）来研究，分析和确认使用R11化合物修复AA-5083合金的效果。修复效率达到96％。
