Abstract

In the present invention, sol-gel method was employed to prepare a polymer-silicon dioxide composite solution, which was dipped coated on the surface of the iron plate. After drying, evenly distributed nano particles were observed in the film under a scanning electron microscope. This film has ability to resist the corrosion of the iron surface. It passes through the method of neutral salt spray testing for more than 1000 h that is the National Standard Serial (CNS) number: 8886; Class-mark: Z8026. Under (CNS) number 10757; Class-mark: K6801, 1 kg pencil hardness test, 8 H is obtained for the film. By the adhesion tape test, according to ISO 2409 and 1992(E), less than 5% areas are removed. Comparing the open circuit potential (EOCP) versus time, corrosion current density (J/Amp*cm<SP>2</SP>) vs. over potential (η a) for the covered and uncovered Fe plates, it also confirms the corrosion resistance of the iron plate by the coated film.
