TEM Examination of the Film Formed on Corroding Mg Prior to Breakdown
Bibliographic record
Abstract
The composition and structure of the film formed on Mg corroding in 0.01 M NaCl prior to any visible localized breakdown event was examined using a transmission electron microscopy (TEM). Focused ion beam (FIB) milling was used to prepare electron transparent lamellae of the film in cross-section. The TEM examination revealed that the film was comprised chiefly of a magnesium oxide (MgO) region adjacent to the Mg-film interface and a more porous mixed MgO and magnesium hydroxide [(Mg(OH)2] region adjacent to the film/electrolyte interface. It is suggested that Mg corrosion involved both MgO film formation (anodic oxidation) and dissolution (chemical hydration) processes. EDS revealed that chlorine (Cl) was present throughout the film. This suggested that chloride ions (Cl−) were incorporated into the film at potentials not associated with enhanced localized corrosion, likely as a precursor to breakdown.

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.
