In high-temperature applications specifically in solid oxide fuel cells, the utilization of ceramic coatings on metal substrates is utmost importance as it provides significant resistance to oxidation. this study, for first time, a simple and effective electrophoretic deposition approach used fabricate dense La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) treated with methyl hydrogen polysiloxane (MHP). The structural morphological analysis pre-and post-treated LSCF are extensively investigated using XRD, Raman spectroscopy, XPS, SEM. Both densification adhesion strength observed be enhanced significantly MHP solution. wetting characteristics coating show remarkable improvement over underlying metallic substrate. After post-treatment binder, oxidation scaling rate was reduced by factor 3.6 2.6 compared bare steel untreated samples, respectively.
