Abstract: The titanate-zirconate phosphonate hybrid films were prepared by two-step method on AA6061 aluminum alloy for corrosion resistance. The morphology of those films was investigated by SEM with the chemical structure analyzed by Fourier transform infrared spectroscopy. Furthermore, the phase composition was examined by X-ray photoelectron spectroscopy with the corrosion resistance performance tested by salt spay test. The results showed that the titanate-zirconate aminotrimethylene phosphonate films are of hybrid/composite structure that is composed of the titanate-zirconate film and aminotrimethylene phosphonate layer. The corrosion area of the hybrid film is less than 10% after continual salt spay for 72 hr.
