Abstract

The objective of this work was to develop new TiO₂-based coatings for producing an effective barrier as well as an appropriate support for inhibitors in corrosion protection of zinc. For this purpose, compact and mesoporous titania coatings on zinc substrates were prepared by sol-gel method (dip coating). For preparing mesoporous layers, cationic (cetyltrimethylammonium bromide, CTAB) or non-ionic (Pluronic PE 10300) surfactant templates were applied. The corrosion behaviour of the coatings was evaluated by open circuit potential measurements and Tafel interpretation of the polarization curves. The best corrosion resistance was noticed in the case of TiO₂ coated samples prepared in the presence of Pluronic surfactant.
