| 摘 要： | 为了解决碳钢在含有NaCl溶液中的腐蚀问题,在硅酸钠溶液中复配其他缓蚀组分,制备环保型复合缓蚀剂.通过Tafel极化曲线,盐水浸泡实验,扫描电子显微镜(SEM)对缓蚀剂的性能进行表征.实验结果表明:在室温条件下含缓蚀剂的NaCl水溶液(质量分数5%)对碳钢的腐蚀速率明显降低,缓蚀率达到85.58%,SEM分析显示碳钢表面形成了一层致密的钝化膜;随着腐蚀体系的温度、搅拌速度升高以及碳钢浸泡时间的延长,缓蚀效率不断下降.

| Abstract: | In order to resist the corrosion of carbon steel in NaCl solutiont,he environmental inhibitor was prepared by add-ing other inhibitors in sodium silicate solution.The performance evaluation of inhibitor was characterized by Tafel polariza-tion curves,salt water immersion tests and scanning electron microscope.The experiment results show that 5% NaCl solution containing inhibitor can decrease the corrosion rate of carbon steel apparently under the condition of indoor temperature.The inhibition efficiency is ... |
