Effect of Electrolyte Flow on the Corrosion Behavior of Magnesium Alloy AZ31B
Bibliographic record
Abstract
The influence of electrolyte flow (3.5 wt% NaCl) on the corrosion behavior of magnesium alloy AZ31B was investigated by using a rotating disc electrode. An increase in flow rate (wall shear stress) of the electrolyte over the alloy surface caused a sharp decrease in the corrosion resistance of AZ31B. This was due to the formation of a progressively thinner and more porous Mg(OH)2 film and due to the physical removal of the film by the flow-induced shear stress, reaching a plateau at ca. 2,500 rpm. An empirical equation that models the AZ31B corrosion rate as a function of rpm was proposed. Surface characterization indicated that the nonuniform degradation of the alloy surface was dominated by filiform corrosion and an eventual lateral growth of stable pits at higher rpms. With an increase in rpm, the surface area influenced by the corrosion also increased.

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.
