1. Introduction: Metal Dusting—Continuous Catalyst Generation Metal dusting refers to a severe form of corrosion wherein carbon deposition is accompanied by disintegration of the substrate. Mechanistic details are yet under study, but general steps involve cementite formation with dusting resulting from the associated volumetric expansion accompanying the formation of graphite [1,2]. Presumably, the graphite forms by breakdown of the cementite, aided by graphite nucleation.
