High-temperature corrosion stability diagrams

Stability diagrams for Cr- and Al-containing phases in Na2S04 melt at 900°C (a) Cr-containlng phases and (b) Al-containing phases. (From Kofstad, R, High Temperature Corrosion, Elsevier Applied Science, London, 1988.)... [Pg.599]

It may be summarized that fused salt chemistry coupled with electrochemistry are operating in hot corrosion. High-temperature Pourbaix diagrams representing phase stabilities for A1 in Na2S04 at 906°C and NiO in Na2S04 have been used to estimate... [Pg.63]

Since the corrosion of metals in helium is highly sensitive to environmental parameters, the large number of experimental results has been fairly scattered. Schematic maps, namely Ternary Environmental Attack (TEA) diagram [3, 4, 8] and modified stability diagram [7, 9], were therefore introduced in order to correlate the surface reactivity of Ni-Cr-Mo alloys with the levels of the main gaseous impurities at given temperature and given chromium activity. Those maps delineated domains for the stable Cr compounds (metal, oxide... [Pg.479]
