Effect of solution concentration on the structures and corrosion inhibition behavior of γ-APS films fabricated on surface of low carbon steel was systematically studied by EIS, RA-IR, and AFM. The experimental results indicated that the impedance of γ-APS silane treated substrates and the cross-linking degree of γ-APS films gradually increased with the increasing solution concentration. There was some noticeable transformation in molecular orientation and protective performance of γ-APS films when solution concentration was above 10vol%. High cross-linking degree and changes in molecular orientation generated γ-APS films with excellent protective performance and ordered arrangement.
