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.
