Abstract

Nanostructured TiO2 thin films were deposited on AISI 304 austenitic stainless steel by sol-gel process, dip coating technique. Influence of the number of layers, addition of polyethylene glycol (PEG) in initial sol, morphology and the surface roughness parameters of titania films on corrosion resistance of coated stainless steel were examined. Prepared films were characterized by SEM-EDS and AFM analysis. Electrochemical corrosion behavior of the coated stainless steel substrates was evaluated in simulated marine environment in 3wt. aqueous NaCl solution by electrochemical impedance spectroscopy (EIS) and in 0.5M aqueous HCl solution by potentiodynamic polarization.
