Several synthesis methods such as plasma enhanced, laser ablation, catalytic or thermal chemical vapor deposition, electric arc discharge have been explored for production of high quality carbon nanotubes of different diameters and lengths. Of these catalytic chemical vapors deposition has been proven to produce high quality and large scale CNTs at lower cost. In this paper, a uniform coating of multi-walled carbon nanotubes was directly formed over a steel substrate at 800 degrees by decomposition of ferrocene-benzene mixture which was kept inside a chemical vapor deposition setup. The nanotubes formed over the substrate were characterized using scanning electron microscopy and transmission electron microscopy techniques. Corrosion behavior of the bare and MWCNT coated mild steel substrate was examined through potentiodynamic polarization method. A significant increase in the corrosion resistance was noted with carbon nanotubes coating over the steel plate.
Sweety Arora is currently pursuing PhD at Indian Institute of Science, Bangalore. She is working on developing corrosion resistant coatings using carbon nanotubes and graphene oxide as a filler material in metallic coatings over mild steel substrate.
