Abstract
分别采用大气等离子喷涂APS和带延长Laval喷嘴的大气等离子喷涂制备了Al2O3-3％TiO2涂层，对涂层的相组成、显微结构、结合强度、显微硬度等进行了评价，并和常规大气等离子喷涂氧化铝涂层的性能进行了对比，根据粒子在焰流中的特征对涂层性能差异进行了讨论。结果表明，两种Al2O3—3％TiO2涂层均以卜Al2O3为主，其中还含有少量的α-Al2O3和微晶或非晶。带Laval喷嘴APS所制备涂层的孔隙率、显微硬度和结合强度均明显劣于普通APS涂层，但前者涂层的沉积率达到70％，明显高于后者，大大降低了涂层的生成成本。粒子特征分析表明，延长的Laval喷嘴降低了粒子在等离子焰流中的速度，延长了粒子在焰流中的停留时间，从而使涂层的结合强度和致密度降低，而使涂层沉积率有明显升高。

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.
