In this paper, an optical waveguide sensing scheme for metal corrosion monitoring is proposed, in which a metal film layer is partially substituted for a medium cladding of an optical waveguide to form a corrosion-sensitive film to obtain metal corrosion information. According to the waveguide theory, Of quartz glass as the optical waveguide material, the electrochemical corrosion of Fe C alloy film is formed on the inner surface of the waveguide material, and the structure of the film layer is analyzed by XRD, EDX etc. Electrochemical etching film is simultaneously recorded by optical method Optical waveguide output optical power changes, the experimental results show that the electrochemical method and the optical method to obtain the corrosion information synchronization, the proposed sensing scheme is feasible
