Erosion–corrosion of aluminium alloys in ethylene glycol–water solutions in absence and presence of sand particles
Bibliographic record
Abstract
The erosion–corrosion of aluminium alloys in ethylene glycol–water solutions that simulated the automotive coolant was studied by a rotating cylinder electrode (RCE) through the measurements of potentiodynamic polarisation curves, electrochemical impedance spectroscopy and weight loss. In the absence of sand particles, the turbulent flow developed on RCE produces weakening effects and damage to the oxide film on the Al electrode, which becomes more active with the increasing fluid flow, as indicated by the negative shift of corrosion potential and the decreasing film resistance. In the presence of sand particles, both the turbulent flow of solution and the mechanical impingement of sand particles contribute to the weakening and damage to the oxide film. However, the interfacial reaction mechanism is not changed upon the sand addition. In the ethylene glycol–water–sand solution, weight loss of Al alloys is mainly due to the contribution of the mechanical erosion of sand particles. The corrosion induced weight loss is negligible.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
