Title (EN) A METHOD OF PROVIDING A GRAPHENE COATING ON A CARBON STEEL SUBSTRATE
(FR) PROCÉDÉ DE FOURNITURE D'UN REVÊTEMENT DE GRAPHÈNE SUR UN SUBSTRAT EN ACIER AU CARBONE
Abstract: front page image
(EN) A method of providing a graphene coating on a carbon steel substrate, at least comprising the steps of (a) providing a carbon steel substrate; (b) heating the carbon steel substrate as provided in step (a) in an oxygen-free chamber in the presence of a carbon source to a temperature above 800℃, thereby obtaining a heated carbon steel substrate; (c) decreasing the surface temperature of the heated carbon steel substrate as obtained in step (b) to lower than 700℃ at a cooling rate of at least 1℃/s, thereby obtaining a cooled graphene-coated carbon steel substrate. The graphene coating reduced the corrosion rate by 54.8%, which confirm the good anti-corrosion ability of the as-grown graphene coating.
(FR) Procédé de fourniture d'un revêtement de graphène sur un substrat en acier au carbone, comprenant au moins les étapes consistant à (a) fournir un substrat en acier au carbone ; (b) chauffer le substrat en acier au carbone tel que fourni à l'étape (a) dans une chambre dépourvue d'oxygène en présence d'une source de carbone à une température supérieure à 800 °C, ce qui permet d'obtenir un substrat en acier au carbone chauffé ; (c) diminuer la température de surface du substrat en acier au carbone chauffé tel qu'obtenu à l'étape (b) à moins de 700 °C à une vitesse de refroidissement d'au moins 1 °C/s, ce qui permet d'obtenir un substrat en acier au carbone revêtu de graphène refroidi. Le revêtement de graphène réduit le taux de corrosion de 54,8 %, ce qui confirme la bonne capacité anti-corrosion du revêtement de graphène tel que développé.
