摘要：

TiO2-Al2O3 nanocomposite coatings have been applied on the surface of 316 L stainless steel by a sol-gel process and dip-coating technique. The film with different compositions and thickness have been prepared. The phase composition and morphology of samples has been analyzed by Simultaneous Thermal Analyzer (STA), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and Fourier Transform Infrared (FTIR) instruments. The corrosion resistance of the coatings in 0.5 M NaCl was evaluated by electrochemical polarization measurement. According to electrochemical polarization results, three-layer TiO2-20 wt.% Al2O3 nanocomposite film, shows the best corrosion resistance. (C) 2011 Published by Elsevier B.V.
