Abstract The corrosion behavior of A572Gr.65 steel in various artificial soil solutions was studied by means of electrochemical workstation, scanning electron microscopy (SEM), X-ray diffractometer (XRD) and other techniques. The results show that with the increase of pH value, the polarization resistance of A572Gr.65 steel also increases, meanwhile the free-corrosion potential of A572Gr.65 steel moves positively, while the free-corrosion current density decreases. The corrosion resistance of steel in alkaline solution is the best. When the solution is acidic, the main corrosion product is γ-FeOOH. High concentration of H+ can promote the generation of impedance arc and destroy the passive film on the surface of A572Gr.65 steel. In addition, H+ will generate hydrogen in the reaction process, make corrosion products loose, and accelerate the corrosion process. In this process, the hydrogen evolution reaction of cathode is the controlling step for the whole process. When the pH value becomes neutral or alkaline gradually, OH- will promote the transformation of γ-FeOOH to dense Fe3O4 and α-FeOOH. The dense corrosion products will hinder the diffusion of corrosive ions and dissolved oxygen, protect the substrate effectively and slow down the progress of corrosion. In this process, the formation of corrosion active points on the metal surface and the dissolution rate of anode are the controlling step for the whole process.
