| Abstract: |
| Objective To prepare TiO2 / glass flake composite particles in order to improve the interface properties of glass flake and the coating, and enhance the anti-penetration capability of the composite coating. Methods A layer of TiO2 film was prepared on the surface of glass flake by Sol- refluxing method, and the surface state of the TiO2 film was characterized by SEM,EDS and XPS. The composite coating was prepared and its anti-penetration ability was tested by EIS and salt spray test, and contrasted with that of glass flake. Results The surface of glass flake was coated by TiO2 film, and the TiO2 film connected with glass flake through Si—O—Ti chemical bond. After immersing in salt solution for 15 d, Zw of glass flake coating was 8781 Ω,and that of TiO2 / glass flake coating was 75234 Ω. After salt spray test, the metal protected by TiO2 / glass flake coating was nearly not corroded. Conclusion The glass flake, coated by TiO2 film, had strong anti-penetration ability. |
