Hydrothermally synthesized boron carbide samples are subjected to morphological and structure characterizations before using it as a target for RF sputtering. Boron carbide films prepared on mild steel are further characterized by field emission scanning electron microscopy and Fourier transform infrared spectroscopy. The mild steel plates with and without coating are subjected to corrosion studies with and without an electric field. In both cases, the samples with boron carbide coating exhibit good corrosion resistance. The goniometer study of the contact angle shows the hydrophobic nature of the boron carbide coating. Thus, the study reveals the potential of green synthesized boron carbide for corrosion resistance thin film coating applications. </p>
