摘要/Abstract

摘要： 熔盐是一种高效传热蓄热工质,其在熔盐传热蓄热系统中对熔盐泵、阀门、各种传感器、管道等金属材料设备的腐蚀特性是熔盐应用的限制因素之一,因此确定熔盐对金属材料的腐蚀性能至关重要。为研究四元溴化盐对碳钢(Q235)的高温腐蚀性能,以浸没法在450℃温度下进行碳钢样片的静态腐蚀实验,得到样片在溴化盐腐蚀环境中的腐蚀动力曲线,并对样片腐蚀区域进行扫描电镜和X射线物相分析。实验结果表明,在高温溴化盐腐蚀环境中,碳钢样片被腐蚀的质量损失量随时间延长而增加,腐蚀360h后样片质量损失达到24.14mg/cm²;样片表面产生了电化学腐蚀,腐蚀产物以铁、锰的氧化物为主。

Abstract: Molten salt is a high-efficiency medium for heat transfer and storage.In systems for heat transfer and storage with molten salt, corrosion characteristic of molten salt on metal devices such as molten salt pumps, valves, all kinds of sensors and pipelines is a limiting factor to application of molten salt, so it is important to identify corrosion behavior of molten salt.Carbon steel is the most widely used metal material to make above devices, and study on corrosion characteristics of carbon steel in bromide salts has been relatively deficient.To investigate corrosion characteristics of quaternary bromide salts, static corrosion tests of carbon steel(Q235) were performed in quaternary bromide salts at 450℃ with immersion method, and corrosion kinetic curve of carbon steel samples was gained.Corroded areas were analyzed by scanning electron microscope (SEM) and X-ray diffraction (XRD).The results indicate that weight loss of carbon steel samples by corrosion increase with the extension of time and reach 24.14mg/cm² after 360h in high temperature corrosion environment.The corrosion products mainly contain iron oxide and manganese oxide.
