Abstract
The effects of corona-discharged atmospheric plasma treatment on the surfaces of polyvinyl chloride (PVC) were studied for their application in adhesively joining PVC with AA 6061 aluminium alloy. Although no alteration has been observed in the topography of the treated PVC surfaces, ATR-FTIR analysis reveals the incorporation of –OH functional groups. Therefore, the untreated hydrophobic surface of PVC changes to a hydrophilic nature after corona treatment. Single lap shear (SLS) specimens were prepared using treated PVC and Al bonded with a room temperature cure epoxy adhesive. The obtained SLS strength of the joint between 20-second treated PVC and etched Al is found to be 15 times larger than that of untreated PVC with as-received Al.

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
