Graphene is an atomic layer material with interesting properties due to the regular arrangement of carbon elements. Graphene is prepared by chemical vapor deposition (CVD) on copper or nickel thin film surfaces. Graphene is expected to be effective as a corrosion-resistant film due to its high gas barrier property. In this study, we explored the conditions for graphene deposition on the surface of steel plates with a thickness of 3.0 mm using the chemical vapor deposition (CVD) method. Although graphene deposition on thin steel sheet surfaces with a thickness of about 0.2 mm has been reported from previous studies, graphene deposition on thick steel sheets with a thickness of 3.0 mm has not been technically established. The deposited graphene was confirmed by optical microscopy and Raman spectroscopy. The tensile strength of the graphene-coated steel was also evaluated by tensile strength evaluation tests, and it was confirmed that the maximum stress was about twice that before the coating treatment.
