A kind of silane passivation solution consisting of silicone resin and inorganic metal was prepared, which could used to form organic-inorganic hybrid membrane on the surface of type DC01 cold rolled plate. The effects of pH of silane passivation solution and metal ions content on corrosion resistance of cold rolled plate were also studied. In addition, an infrared spectrum of the silane hybrid membrane was analyzed, and the microscopic morphology of hybrid membrane was characterized by SEM. The electrochemical analysis of the cold rolled plate coated with passivation solution was conducted, and the effect of different composition of passivation solution on corrosion resistance performance of cold rolled plate was explored by open circuit voltage, alternating impedance and polarization curve. The result showed that the corrosion resistance of cold rolled plate was good when the pH of passivation solution was 4.0 and the content of metal cerium was about 15%.
