Corrosion Behavior of Metallic Materials for Innovative Gasification Processes

Abstract: Corrosion Behavior of Metallic Materials for Innovative Gasification ProcessesMetallic materials for highly stressed oxygen nozzles and recovery boilers were studied in respect to their corrosion resistance in H 2 /H 2 O/H 2 S laboratory test gas. Screening tests using ferritic and austenitic steels and nickel-base alloys were carried out and from the results promising alloys selected and tested at various temperatures. With one exception, all alloys show bell-shape temperature dependence of the oxidation kine… Show more

“…By additions of W, Nb and Si, increased mechanical properties, mainly improved creep resistance [26,[28][29][30], are achieved through solid solution hardening and precipitation strengthening by intermetallic Laves phase particles. At temperatures up to 900 • C, an oxide bi-layer consisting of Cr-Mn spinel forms on top of a thermodynamically stable (in air and H 2 /H 2 O/CO/CO 2 /N 2 mixtures) chromia layer [30][31][32][33][34]. The chemical composition of Crofer ® 22 H is presented in Table 1.…”
