研制了一种基于光纤布拉格光栅（FBG）的钢筋腐蚀传感器。在金属化的光纤光栅上电镀一层Fe-C膜，制成了钢腐蚀传感器。已在控制氯离子和氧气可用性的机柜中对涂覆的FBG传感器进行了测试。通过光学显微镜和SEM成像研究了微观结构的变化。FBG光谱由光谱仪采集。结果表明，光谱的变化、波长的偏移以及多峰的出现与Fe-C膜的腐蚀程度有关。(C)2011爱思唯尔有限公司保留所有权利。
A steel corrosion sensor based on fibre Bragg gratings (FBGs) has been developed and tested in this paper. The steel corrosion sensor has been formed by electroplating a Fe-C film on a metallized FBG. The coated FBG sensors have been tested in cabinets in which the availability of chloride ions and oxygen are controlled. The microstructural changes have been investigated by optical microscopy and SEM imaging. The FBG spectra are collected by a spectrometer. The results show that the spectra change, the wavelength shift, and the occurrence of multiple peaks are related to the corrosion degree of the Fe-C film. (C) 2011 Elsevier Ltd. All rights reserved.
