We compare the wetting, morphology and anticorrosion properties of fluorosilane-modified TiO2 (FAS-TiO2/epoxy) and as-received TiO2/epoxy coatings. An array of double-layer TiO2 nanoparticles of two sizes (30 nm and 300 nm) were spin coated onto a steel substrate AISI 316L. The static water contact angles were measured to evaluate the wetting properties of the FAS-TiO2/epoxy (hydrophobic) and the as-received TiO2/epoxy (hydrophilic) coatings. The morphology of the coatings was analyzed with average surface roughness (Sa) measurements and SEM imaging. We show that the order of the deposition in a double layer composed of dual-size nanoparticles plays an important role in the surface roughness and hence the wettability. SEM images reveal a typical morphology and Sa difference between the FAS-TiO2/epoxy and the as-received TiO2/epoxy coatings, reflected in the discrepancy of the average size of the agglomerates that are coating the substrate. Potentiodynamic measurements show an enhanced corrosion resistance for the FAS-TiO2/epoxy-coated AISI 316L stainless steel compared to the as-received TiO2/epoxy-coated AISI 316L.

TiO2 nanodelce dveh velikosti (30 nm in 300 nm) smo na jekleno podlago tipa AISI 316L nanesli s "spin coaterjem". Omo~itvene lastnosti prevlek smo dolo~ili z meritvami stati~nih kontaktnih kotov. Le-te so pokazale hidrofobno naravo FAS-TiO2/epoksi prevlek in hidorfilno naravo~istih TiO2/epoksi prevlek. Morfolo{ke lastnosti prevlek smo analizirali z meritvami povpre~ne hrapavosti povr{ine (Sa) ter SEM-mikroskopijo. Pokazali smo pomen vrstnega reda nalaganja nanodelcev dveh velikosti na hrapavost povr{ine in njeno omo~ljivost. SEM-posnetki prikazujejo razliko v morfologiji in hrapavosti povr{in FAS-TiO2/epoksi in~istih TiO2/epoksi prevlek, ki se odra`a v tvorbi aglomeratov razli~nih velikosti na eni in drugi povr{ini. Potenciodinamske meritve ka`ejo izbolj{ano odpornost proti koroziji FAS-TiO2/epoksi prevlek v primerjavi s~istimi TiO2/epoksi prevlekami na jekleni podlagi tipa AISI 316L.
