Abstract
The work focuses on producing and investigating the mechanical, wear, and microstructure of Al7075 alloy nano-sized Alumina Oxide (n-Al2O3) particles with wt. % of 1, 2, and 3. Metallurgical methods have been used to create Al7075/n-Al2O3 composites. The microstructure showed that n-Al2O3 was distributed uniformly. Tests were done on a tribometer that was fastened to a hard steel disk to examine wear loss. In response to the surface approach, the wear parameters were optimised using the Taguchi L27 orthogonal array. The obtained result indicates that, hardness and tensile strength increase by 40% & 31% respectively. It is due to the increase of wt. % hard ceramic nano particulates. The Analysis of Variance (ANOVA) result indicates that, wt. % of n-Al2O3 is the most significant (61.02 %). With 95% reliability, the constructed model successfully predicted the wear rate, & ANOVA was used to corroborate the outcomes of all models.

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
