Corrosion Resistance of TiO2-ZrO2 Nanocomposite Thin Films Spin Coated on AISI 304 Stainless Steel in 3.5 wt. % NaCl Solution

Utilizing high chromium and nickel content in AISI 304 steel confers its good corrosion resistance. However, the high content of chromium and nickel increases the steel susceptibility to corrosion caused by the high concentration of chlorine. Consequently, the electrochemical and mechanical performance of the steel degrades. In this study, the effect of adding a layer containing a gelatin-dispersed mix of TiO2-ZrO2 nanoparticles on the corrosion rate and critical pitting potential of AISI 304 steel is studied. Two mix ratios of TiO2-ZrO2 nanoparticles to gelatin (0.5:0.5, 0.3:0.7) were used. T...
