Abstract Scope Steels and Ni-base alloys are aggressively attacked by metal dusting between 450 and 750C in carbonaceous gas environments that are common to the energy and processing industries. Carbon from the gas first deposits, then diffuses inwards and finally disintegrates the material by internal graphite formation. Protection of the alloys from metal dusting can be achieved by Cr2O3 and/or Al2O3 scale formation. The oxide scale is formed in situ and its properties may thus depend on the amount of H2, CO, CO2, and H2O in the gas. The structure of oxide scales on alloy 601 formed in four gas mixtures with varying aggressivity is analyzed. SEM, XPS, and TEM are applied to characterize the morphology of the oxide scales, which are unevenly thick and contain metallic particles in the outer layer. This understanding is then applied to compare the metal dusting behavior of conventional and additively manufactured (AM) alloy 699XA.
