Abstract
High-velocity oxygen Fuel (HVOF) is a coating process that produces a dense, tightly bonded layer that significantly enhances wear resistance on the coated component. Our partner, the National Research Council of Canada (NRC), develops innovative HVOF coating methods for cylindrical parts' internal surfaces used in critical applications such as landing gear components. However, to be adopted by the aerospace industry, it is necessary to demonstrate that these HVOF-coated parts can be reliably inspected using non-destructive testing (NDT) techniques. Although inspections using conventional ultrasonic of HVOF-coated parts are already well established, phased array ultrasonics (PAUT) have the potential to increase inspection productivity, defect detectability and traceability. Therefore, this study focused on the evaluation of PAUT methods performance for assessing internally coated cylindrical components in terms of defect type, size and orientation.

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
