Graphene is a typical two-dimensional layered material that exhibits unique properties. We have studied the growth of graphene for use in corrosion-resistant coatings on steel substrates formed by chemical vapor deposition (CVD). The results showed that graphene films coated on steel substrates exhibit high corrosion protection in hydrochloric acid solutions. However, details of the graphene growth behavior on steel substrates were not well understood. Since the graphene growth is related to the deposition conditions, such as amount of carbon supply and temperatures etc., this study mainly investigated the effect of carbon supply time on the coverage in graphene deposition. Graphene begins to grow on the steel substrate at carbon supply time spans between 10 and 20 min. Graphene coverage increased as the carbon supply time increased, but it became difficult to increase the coverage when the carbon supply time exceeded 45 min.
