The influence of chromium and molybdenum on the repassivation of nickel‐chromium‐molybdenum alloys in saline solutions
Bibliographic record
Abstract
The electrochemical properties and compositions of passive, transpassive, and re‐formed passive oxides on the Ni‐Cr‐Mo alloys C22 (high Cr/low Mo) and HYBRID BC1 (low Cr/high Mo) have been studied in 5.0M NaCl solutions. At low potentials in the passive region, the oxide was less resistive on BC1 compared to C22, possibly due to the influence of Mo in increasing the number of defects in the oxide. At higher potentials in the passive region, both alloys exhibited similar behaviours and composition of oxide films. Under transpassive conditions, the Cr III barrier layer (dominantly Cr 2 O 3 ) was destroyed on both alloys, with a greater accumulation of Mo VI /Mo V on the BC1 than on the C22 alloy. Improved passivity was achieved for both alloys on returning to potentials in the passive region. This appears to be due mainly to the re‐formation of the Cr III barrier oxide layer on C22, but to a combination of the reformation of this layer and the accumulation of Mo VI /Mo V on the BC1.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
