| Abstract | The corrosion processes of two kinds of weathering steels, Q400NQR1 and 09CuPCrNi, in 2.0% NaCl neutral solution were studied with electrochemistry impedance spectrum technique, and an equivalent electric circuit model was proposed, which is based on the physicochemical process of the corrosion, to analyze the evolution features of the corresponding electrochemical parameters. The results show that the whole corrosion process of weathering steels can be divided into four segments: metstable-pitting region, stable pitting region, medial corrosion region and general corrosion region. Q400NQR1 possesses higher anticorrosion ability than 09CuPCrNi due to the formation of the denser inner corrosion products layer, which covered on the surface of the Q400NQR1 substrate and inhibited the diffusion of the corrosive species from the environment to the substrate. |
