Sono-Immersion Deposition on Magnesium Alloy
Bibliographic record
Abstract
Coating is a viable way to improve the corrosion resistance of magnesium alloys for aerospace and automotive applications. This paper presents the acoustic effect on the copper immersion coating of AZ91 magnesium alloy. Electrochemical impedance spectroscopy and open-circuit potential measurements were conducted to characterize the copper immersion-coating processes. The surface morphology changes of the copper immersion coatings obtained with and without sonication were examined using scanning electron microscopy. All experimental results have clearly demonstrated a significant increase of surface coverage on magnesium alloy. Data analysis indicated that formation of a surface film on the uncoated magnesium area during immersion coating under nonsonicated condition restrained magnesium dissolution which, in turn, limited the deposition process. The application of sonication induced asymmetric cavitations at the interface and efficiently destroyed or prevented the formation of a surface film. As a result, the anodic reaction (magnesium dissolution) was maintained to provide a continuous driving force for cathodic copper reduction and deposition, hence increasing the surface coverage. © 2005 The Electrochemical Society.

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.
