The problem: While the most effective (and possibly industrially viable) graphene coatings are achieved by the chemical vapour deposition (CVD) of graphene. Fe and its alloy such as mild steels have very high solubilities of carbon at the temperatures at which CVD process for graphene deposition is accomplished (650-1000 Degree Celsius) and also cooled. Dissolved carbon is rejected rapidly during cooling, resulting in formation of carbon soot at the surface (instead of forming thin graphene layer). Our solution: We have developed a coating process which overcomes this problem and allows graphene to be deposited by CVD. Our graphene coating provided x100 fold superior corrosion resistance in comparison to the bare mild steel, as demonstrated by the potentiodynamic polarization plots.
