摘　　要：用PVD法制备光纤腐蚀传感器 (FOCS)的Fe C合金敏感膜 ,在光纤纤芯上得到厚度大约 1 μm的Fe C合金膜 ,而且光信号对敏感膜的腐蚀信息有响应 .为了增加敏感膜的厚度 ,根据平面波导与圆柱波导的相似性 ,采用PVD与电镀复合的方法在平板石英玻璃上制备Fe C合金膜 ,研究该膜层的形貌、结构和在不同NaCl溶液中的耐蚀性 .结果表明 :复合制备的Fe C合金膜的结构和耐蚀性与普通碳钢近似 ,并初步监测了光信号对敏感膜腐蚀信息的响应 。A Fe-C alloy corrosion sensing film of the Fiber Optical Corrosion Sensor (FOCS) was fabricated by PVD on the fiber core. The thickness of this film is about 1 μm and the optical signal can respond to the film's corrosive information. Furthermore, on the basis of the comparability between the planar wave-guide and column wave-guide, a method of PVD and its incorporation with electroplating was used to fabricate the Fe-C alloy film onto quartz in order to increase the film thickness. The surface morphology of electroplating the Fe-C alloy film was investigated by metallographic microscopy. The structure of film was studied by X-ray diffraction and an electrochemical method was used to evaluate the corrosion resistance of the Fe-C alloy film in NaCl (sodium chloride) solution of different concentration. The initial results showed that the structure and corrosion resistance of the Fe-C alloy film were close to that of carbon steel, and the response between the optical signal and corrosion information of film could be detected. These data have formed the basis of a FOCS.
