The hydrolysis conditions of 3,3’-bis[triethoxysilylpropyl]tetrasulfide (Si-69) were probed by the orthogonal design. The influence of film-forming factors such as the dosage of Si-69, the PH value of hydrolization, the time of hydrolization, the aging time and the aging temperature on the corrosion resistance of silane films was also studied. The best anti-corrosion technology was systematically identified. The electrochemical tests showed that the silane films effectively reduced the surface porosity of aluminum 2024 and prevented the cathode active sites reduction reaction which the corrosion particles participated in.
