Abstract
Al2O3-3 % TiO2 coatings were prepared by conventional air plasma spray (APS) and air plasma spray with extended Laval nozzle in this paper.The phase composition,microstructure,adhesive strength and micro-hardness for the two techniques were characterized respectively by comparing with those of conventional APS Al2O3 coating.The significant difference between two Al2O3-3 % TiO2 coatings was investigated according to in-flight characteristic in plasma plume.The results showed that both of Al2O3-3 % TiO2 coatings were mainly composed of γ-Al2O3,and a small fraction of α-Al2O3 and fine crystal or noncrystal were also found in the coatings.APS with extended nozzle sprayed coatings exhibited worse properties in porosity,microhardness and adhesive strength than conventional APS,but the deposition efficiency for the former was obviously higher than the latter,which reached 70 % and greatly lowered the cost of coating production.Particle characteristic revealed that extension of nozzle decreased the in-flight velocity and prolonged the duration in plasma plume,which resulted in the decrease of adhesive strength and density and the increase of deposition efficiency.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
