| Abstract: | Using EIS technique , the corrosion mechanism of heavily anticorrosion ceramic painting in 3.5 % NaCl was studied. It is found that the corrosion resistance of the heavily anticorrosion ceramic coatings used in the protection of inner wall of pipeline is excellent . The electric resistance is as high as 109Ω and remains unchanged when soaked in NaCl solution for a long period. It can be said that the heavily anticorrosion ceramic coatings possess very high insulation performance , antipermeability and good corrosion resistance. |
