Paper Abstract

The feasibility of an optical fiber corrosion sensor(OFCS) is studied in the present paper. A multi-mode fiber is metallised by physical vacuum deposition(PVD) and electroplating a Fe-C alloy film on an uncladded part with 1-2cm length. Comparatively, similar methods used to form metallic film on planar quartz crystal. Electrochemical measurements including continuously inspection of electrochemical parameters show different characters between cylindrical and planar wave guide. The shift of light power transmitted through the fiber is registered with corrosion. Microanalysis is carried out to show the metallised film’s forming. Electrochemical process of the corrosion on the fiber is researched by continuously monitoring open potential Ecorr and linear polarized resistance Rp.
