    摘要: Coated steel articles are described which exhibit anti-coking properties, and a process for producing such articles by depositing an anti-coking coating on a matrix constituted by a steel, in general a refractory steel. These articles comprise: a refractory steel substrate comprising at least 0.2% by weight of carbon; a carbon-rich diffusion barrier; and an outer layer containing 90% to 99% by weight of chromium, coated by a cementation method. More particularly, the coated steel articles constitute tubes for reactors or stills used in various refining or petrochemical processes.
