Abstract
Cold spray is an innovative coating technology mainly based on the high speed impact of metallic particles on various substrates. Low temperature carrier gases (air, He and N 2 ) accelerate particles (usually 1–50 μm in diameter) to high velocity (typically 300–1200 m s − 1 ) that is generated through a convergent–divergent de Laval type nozzle. Particles' severe plastic deformation occurs at temperature well below the melting point leading to the unique mechanical properties experienced by cold spray coatings. In the recent past, different papers were published describing the fatigue properties of cold sprayed metals and alloys. Generally, mechanical results are related to the microstructural evolution due to different coating materials and different processing parameters. The present paper presents a critical review of the results belonging to the available literature on fatigue properties of cold sprayed coatings.

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
