Effect of Buffer Capacity on Electrochemical Corrosion Behavior of Alloy 800 in Sulfate Solutions
Bibliographic record
Abstract
Abstract Electrochemical corrosion behavior of Alloy 800 (UNS N08800) in sulfate solution was compared in the presence and absence of potassium phosphate monobasic/sodium hydroxide (KH2PO4/NaOH) buffering reagent. Cathodic polarization, cyclic voltammetry, and electrochemical impedance spectroscopy were used to characterize the behavior of hydrogen peroxide (H2O2) reduction in buffered and unbuffered solutions. Open-circuit potential measurements, polarization resistance, electrochemical impedance spectroscopy, and potentiodynamic polarization were utilized to evaluate the corrosion behavior of Alloy 800 as affected by the buffer reagent. Results showed that reduction of H2O2 takes place at higher potentials and with lower charge-transfer resistance in buffered solutions. The Alloy 800 passive layer thickened in the presence of the buffering reagent and showed lower corrosion rate. The overall anodic potentiodynamic behavior was similar in both the buffered and unbuffered solutions. Because of its bufferi...

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
