Abstract
The structure and properties of coatings formed on 2ххх and 7ххх aluminum alloys by plasma elec-trolytic oxidation (PEO) performed under the same conditions have been studied. The substrate material is shown to substantially affect the quality, structure, and properties of formed coatings. Compared to the D16 Т (4Cu, 1.4Mg wt %) alloy substrate, the V95 Т1 (6.2Zn, 2.4Mg, 1.7Cu wt %) alloy substrate favors the for-mation of coatings with a more homogeneous composition and uniform thickness, which exhibit great cohe-sive and adhesive strength and mechanical and tribological properties. The adhesive failure of PEO coatings formed on the V95 Т1 alloy occurs at a load of 63 N, which is substantially higher than the critical load (49 N) of coatings formed on the D16 T alloy. The maximum hardness of coatings formed on the V95 Т1 alloy is 25 GPa, which exceeds that of coatings formed on the D16 T alloy and is equal to 20 GPa. The wear resistance of coating in water, which is formed on the V95 Т1 alloy is 4.4 times higher compared to that of the wear-resistant coating formed on the D16 T alloy.

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
