H. P. Seitsonen, Science 2002, 297, 2003. 1 Introduction Metal dusting is a catastrophic corrosion process leading to the disintegration of iron-, nickel- and cobalt-based alloys in strongly carburising gas atmospheres (carbon activity aC > 1) at moderately high temperatures (400–800°C). For iron-based alloys, the proposed mechanism [1–4] involves the super-saturation of iron with carbon and subsequent formation of cementite at the surface. This metastable cementite decomposes as the carbon activity in the cementite/ graphite interface is lowered to unity when graphite deposits on the cementite surface.

The coating did not act as a water vapor barrier, with significant accelerated/non-protective SiO 2 growth evident below. Although these results indicate this approach is not promising for environmental barries coating EBC applications, self-graded oxide coatings were successfully formed from the deposited metallic precursor alloys, and there may be other applications where such an approach may be of interest. For the EBC application, a variation on conventional metallic coating strategy was subsequently investigated [13].
