Sažetak
In this paper, one layer and three layers of yttria stabilized sol-gel ZrO2 thin films were deposited on the X2CrNiMo17-12-2 (AISI 316L) austenitic stainless steel by dip coating method. For the preparation of sol zirconium(IV) butoxide was used as pre-cursor, i-propanol as a solvent with addition of nitric acid as a catalyst, acetylacetone as chelating agent and water for hydrolysis. Deposited films were calcined at the temperature of 400 °C. Thickness of sol-gel ZrO2 films deposited on stainless steel was determined by glow-discharge optical emission spectrometry (GD-OES). It was found that thickness of deposited films increases by increasing the number of layers. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization in simulated marine environment (3.5 wt. % NaCl aqueous solution) were used to de-termine the corrosion behaviour of ZrO2 coated stainless steel. The influence of ZrO2 layers number on the degree of the protection was examined as well. It was found that the sol-gel ZrO2 films are able to make an appreciable improvement in the corrosion resistance of stainless steel in the investigated corrosive medium.
