The optimal process conditions for preparation of self-assembly film were designed by orthogonal experiment with γ-glycidoxypropyl trimethoxy silane（GPTMS）and the silane films were prepared on the surface of aluminum alloy to improve its corrosion resistance.The corrosion resistance of the optimal films on the surface of aluminum alloy was studied by polarization curveand scanning electron microscope（SEM）. The results indicated that the optimal process conditions were as follows：the pH value of the solution 4. 5，V（GPTMS）∶V（EtOH]∶ V（H2O）=2∶7∶91，T1（hydrolysis temperature）=25 ℃，t 1（hydrolysis time）=7 h，t 2（immersion time）=10 min，t 3（curingtime） = 90 min，T 2（curing temperature）=120 ℃，The silane films on aluminum alloy in this condition provided good corrosion resistance.
