【 摘 要 】

In this paper, a dense structure of Ti-containing organic-inorganic hybrid transparent film was prepared on the surface of 304 stainless steel by sol-gel method combined with organic-inorganic hybridization theory. The basic properties and corrosion resistance of the hybrid film showed a unimodal change with the increase of the precursor content. When the molar ratio of the precursor to tetrabutyl titanate was about 0.75, the hybrid film obtained had the best performance. The microstructure of the film was analyzed by SEM and AFM technology. The Ti-containing organic - inorganic hybrid film was denser than the Si-containing hybrid film and epoxy film, which resulted in better salt spray resistance and EIS performance.
