In this paper, a Fe‐C alloy corrosion sensing film was fabricated on the fiber core by PVD, PVD incorporated with electroplating, and other methods. A Light Power Test System which was composed of a LD lamp‐house, a Bare Fiber Adapter (BFA) and a light power meter was used to detect the changes of lamp‐house's output power in the corrosion process of the Fe‐C alloy film. The major factors that may have some effects on the sensing capability of the Fe‐C alloy film were analyzed. The initial results show that lamp‐house's output power increases gradually with the occurrence of Fe‐C alloy film's corrosion, which accords basically with the sensing principle of the film. There are some diversities in the sensing ability of the Fe‐C alloy film fabricated by different methods. The trend of changes of lamp‐house's output power can be used as a qualitative token of the corrosion information of the Fe‐C alloy film. These data have been used for some elementary preparations for a carbon steel Fiber Optical Corrosion Sensor (FOCS).
