研究了光纤腐蚀传感器的可行性。在1-2cm的光纤上用物理真空沉积和电镀的方法镀上一层Fe-C合金膜，使多模光纤金属化。光纤的未包覆部分。通过光纤传输的光功率的变化与腐蚀有关。进行了微观分析以显示金属化膜的形成。通过连续监测开路电位E-corr、线性极化电阻R-p和电化学阻抗谱，研究了纤维腐蚀的电化学过程。(c)2005爱思唯尔有限公司保留所有权利。
The feasibility of an optical fibre corrosion sensor (OFCS) was studied. A multi-mode fibre was metallised by physical vacuum deposition and electroplating of a Fe-C alloy film on a 1-2cm. uncladded section of an optical fibre. The shift of light power transmitted through the fibre was registered with corrosion. Microanalysis was carried out to show the formation of metallised film. The electrochemical process of the corrosion on the fibre was researched by continuously monitoring open potential E-corr, linear polarized resistance R-p and electrochemical impedance spectra.
