摘要	The corrosion behavior of 907 steel under thin electrolyte layer (TEL) has been investigated by means of cathodic polarization curve measurement, electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM). The results show that the cathodic diffusion current density presents the variation trend of initial increase and subsequent decrease with the decrease of TEL thickness, and the maximum deposits at 58 mu m. The cotangent-hyperbolic impedance (O) is rationally first introduced to study the diffusion process of the reactants through the corrosion products layer with many permeable holes. The initial corrosion rate of 907 steel under different TEL thickness increases with the decrease of TEL thickness except that of 104 mu m, whereas the corrosion rate after long time corrosion can be ranked as 104 mu m > 402 mu m > 198 mu m > 301 mu m > bulk solution.
