摘要	Acid soils in Southeast China are known as one kind of the most corrosion aggressive soils toward pipeline steels. Acid soils have high contents of Fe oxides, especially their electrochemically active phase, like ferrihydrite and lepidocrocite, which will influence corrosion process and induce some new phenomena in the soil corrosion. In this work, Fe oxides residing in the clay minerals of an acidic soil were characterized by XRD and cyclic voltammetry. The electrochemical behavior of API X80 pipeline steel in the soil was evaluated by EIS and Tafel polarization. Cyclic voltammetry shows that Fe oxides were electrochemically active. Redox active nature Fe oxides and their phase transformation occurring in the soil are suggested to simulate the steel corrosion, and a possible electrode reaction series involved in the corrosion process is proposed.
