Electrochemical Impedance Studies of Hot Corrosion of Preoxidized Ni by a Thin‐Fused Na2 SO 4 Film
Open accessAbstract
A thin‐film electrochemical arrangement has been developed to investigate the hot corrosion of preoxidized Ni by a fused film at 1200 K in a catalyzed 0.1% gas mixture. A Pt counterelectrode enables polarization measurements using the three‐electrode configuration as well as open‐circuit potentiometry. To extract mechanistic information without disturbing the system, the electrochemical impedance technique was used. Results of three distinct modes of hot corrosion (passive, pseudo‐passive, and active) resulting from different preoxidation conditions are discussed.

The rate determining step for hot corrosion was not found.
“While equivalent circuits were developed and some important aspects of the hot corrosion process (e.g., diffusion rates of S2O7 2- ) were evaluated, the rate determining step for hot corrosion was not found.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
