Abstract

A protective coating of nano-yttrium titanate was developed for 304 stainless steel under acidic conditions (1.0 M HCl). The nano-yttrium titanate (Y2Ti2O7) was thoroughly characterized using various surface analysis tools, such as X-ray diffraction analysis (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDS). In addition, electrochemical techniques, including Tafel polarization (dc), electrochemical frequency modulation (EFM), and electrochemical impedance spectroscopy (EIS) were employed. The findings demonstrate that the nano-yttrium titanate coating significantly improves the protection efficiency of 304 stainless steel by enhancing its hydrophobic properties
