Abstract
An AC/DC spark anodizing method was used to coat the aluminum-copper (Al-Cu) alloy AA2219 with oxide films to protect them form corrosion. The effect of electrolyte solution composition and the lifetime use of the anodizing solution on the anodizing process and the oxide film properties have been investigated. In this work, an anodizing solution containing 0.15 M KOH and various concentrations of Na2SiO3 has been used. Oxide film characterizations were carried out using scanning electron microscopy (SEM) and energy dispersive x-ray (EDX). Corrosion assessment was carried out using linear sweep voltammetgram (LSV) in borate buffer solution (pH 7).

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 it
