Abstract

Field exposure for carbon steel Q235 and weathering steel 09CuPCrNi-A was carried out in a site of typical urban atmosphere and a site of typical petrochemical environment respectively at Wuhan metropolis in the central China. Whilst the evolution of the formed rust layers on the steels in the initial stage of field exposure was characterized by SEM, electrochemical method and XRD. We found that the evolution of the early rust layers could be differentiated into two stages. The redox reaction was faster in the first stage. In the second stage, the reduzate Fe₃O₄ was accumulated and the oxidation process of Fe₃O₄ was suppressed with the growing of rust layers, thereby the electrochemical activity of the rust layers was enhanced.

Key words: electrochemical polarization curve evolution of rust layer redox of rust layer
