Corrosion Inhibition of Mg Alloy ZEK100 Sheet Metal by Dissolved Lithium Carbonate
Bibliographic record
Abstract
The extent of corrosion inhibition of Mg alloy ZEK100 in 100 mM NaCl (aq) imparted by dissolved Li 2 CO 3 (aq), with a particular focus on Li incorporation into the surface film that forms under activated anodic dissolution (anodic polarization) was determined. Dissolved Li 2 CO 3 reduces corrosion by a factor of ∼12 when added at a concentration (100 mM) just below saturation. Effective inhibition involves suppressing the transition to filament-like corrosion, and associated anode/cathode activation, initiating at local breakdown sites. Such suppression is linked to the formation of Li-doped MgO as a corrosion product film during activated anodic dissolution. When formed by anodic polarization, the film composition also significantly affects the chloride ion distribution with the film. Without Li incorporation, chloride ions tend to enrich at the film/metal interface, whereas with Li incorporation, chloride ions tend to be uniformly distributed within the film.

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.
