Morphology of nanostructured sol–gel TiO2 films on stainless steel

Titania (TiO2) thin films with one-layer and three-layer were deposited on the X5CrNi18-10 (AISI 304) stainless steel by dip coating sol-gel process. For the preparation of sol, titanium isopropoxide was used as a precursor, propanol as a solvent, with addition of nitric acid as a catalyst and acetylacetone for peptization. Deposited films were calcined at the temperature of 550 °C. Scanning electron microscopy (SEM) equipped with EDS detector and atomic force microscopy (AFM) were used for characterization of prepared films. SEM-EDX analysis confirmed the TiO2 films formation. Results obtained by AFM analysis show that the number of deposited layers influenced the surface topography, as well as roughness parameters.
