| Abstract: | Inorganic/organic silicon hybrid materials were synthesized on the chemical modification of silicon sol by siloxane with an organic group. Furthermore silicon hybrid coating with better properties was prepared with selected pigments by orthogonal tests. Experimental results showed that integrative properties of the silicon hybrid coatings were excellent and it was suitable for severe corrosive environments. |
| Keywords: | magnesium alloy sol-gel modification protective coating |
