Research, Development and Application of High-effiency Ultrasonic PlazJet Coating Technique
Bibliographic record
Abstract
According to the design idea of the high_efficiency and ultrasonic plazjet gun, structures of the gun body, water path, air path, the negative and positive poles and the powder delivering structure have been newly designed, and a unique single_negative pole Laval jet has been designed using the plasma physics, fluid mechanics and engineering thermodynamics theories. In the coating specifications detecting of the plazjet gun and the coating, the high_efficiency and ultrasonic spray coating have been realized under low power (80kW) and low air fluid (6m 3/h), and the particle flying speed reaches 450 m/s within the effective spray coating distance. The main specifications of the jet gun such as the flame moving speed, the powder sedimentation efficiency, ratio of the coating energy consumption and the cost efficiency of the pole have reached or surpassed those of the PlazJet high efficiency ultrasonic coating gun of TAFA Company of America. The bond strength, pore space and microhardness of the ceramics coating prepared by this gun are better obviously than the common METCO.9M plasma gun, but the running cost is only the half of the foreign ultrasonic PlazJet coating.

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.
