Abstract

Using ethyl acetoacetate (EAcAc) as a chelating agent, ultra fine TiO_2 sol is prepared. Nano-TiO_2 coatings are deposited on the 316L stainless steel by the dip-coating. Hydrothermal post-treatment leads to crack-free coatings. Meanwhile, the surface struture and properties was optimized. Self-assembly of Hetadecafluorodecyltrimethoxysilane (FSA-13) fabricates hydrophobic layers on the surface of the nano-TiO_2 coatings. Particle sizes of TiO_2 sol was analysed by zeta pals potential analysis, and surface morphology, structure and properties was characterized by contract angle instrument, XRD, and SEM technologies. The results have shown that the surface of coatings is porous, with approx. 375 nm thick, the particle diameters in the range of 18～20 nm evenly and TiO_2 is anstase. Electrochemical measurements show that the hydrophobic coatings have excellent anticorrosion properties.
