Abstract

An automated corrosion monitor, named the Internet of Things atmospheric corrosion monitor (IoT ACM) has been developed. IoT ACM is based on electrical resistance sensor and enables accurate and continuous measurement of corrosion data of metallic materials. The objective of this research is to study the characteristics of atmospheric corrosion by analyzing the acquired corrosion data from IoT ACM. Employing data processing and data analysis methods to research the acquired corrosion data of steel, the atmospheric corrosion characteristics implied in the corrosion data can be discovered. Comparing the experiment results with the phenomenon of previous laboratory experiment and conclusions of previously published reports, the research results are tested and verified. The experiment results show that the change regulation of atmospheric corrosion data in the actual environment is reasonable and normal. The variation of corrosion depth is obviously influenced by relative humidity, temperature and part of air pollutants. It can be concluded that IoT ACM can be well applied to the conditions of atmospheric corrosion monitoring of metallic materials and the study of atmospheric corrosion by applying IoT ACM is effective and instructive under an actual atmospheric environment.

摘要

一种名为物联网大气腐蚀监测仪（IoT ACM）的自动腐蚀监测仪已经研制成功。IoT ACM基于电阻传感器，能够准确、连续地测量金属材料的腐蚀数据。本研究的目的是通过分析从IoT ACM获取的腐蚀数据来研究大气腐蚀的特性。采用数据处理和数据分析方法对获取的钢材腐蚀数据进行研究，可以发现腐蚀数据中隐含的大气腐蚀特性。将实验结果与以往实验室实验现象和已发表报告的结论进行比较，对研究结果进行了检验和验证。实验结果表明，实际环境中大气腐蚀数据的变化规律是合理正常的。腐蚀深度的变化明显受相对湿度、温度和部分空气污染物的影响。可以得出结论，IoT ACM能够很好地应用于金属材料大气腐蚀监测条件，在实际大气环境下应用IoT ACM研究大气腐蚀是有效且具有指导意义的。
