A cryogenic radiometer blackbody cavity comprises a cavity body formed by connecting a side surface (6) of a normal cone, a side surface (5) of a cylinder and a slanted bottom surface (4). An axis (3) of the normal cone and an axis (3) of the cylinder coincide. A generatrix and the axis of the normal cone form an included angle (1). A cavity incident aperture (7) is arranged at the tapered end of the normal cone. A plane in which the cavity incident aperture is located is perpendicular to the axis (3) of the normal cone. The slanted bottom surface (4) and the axis (3) of the cylinder form an included angle (2). The invention adopts a cavity body structure combining a slanted bottom, a cylinder and a cone. The conical light-blocking design can block stray light outside the cavity body, and reduce spilling of reflected light out of the cavity body. An inner wall of the cavity body is coated with a purely specular graphene material, thereby reducing diffuse reflection of optical radiation inside the cavity, and enabling a relatively concentrated temperature distribution and a high temperature response speed.

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.
