Abstract:
<p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;text-align:

of developing boron carbide coating for corrosion resistance. 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>
