Abstract

fetched live from OpenAlex

In this work, the non-uniform corrosion behavior of 6061 Al alloy in mass 3.5% sodium chloride solution under a crevice spacing of d = 206 μm was studied by using wire beam electrode (WBE) method. The combined tests of the WBE with dynamic potential polarization (Tafel) and electrochemical impedance spectroscopy (EIS) curves were carried out, together with a scanning electron microscope (SEM) and an X-ray photoelectric spectroscope. The results showed that the crevice corrosion was not obvious at the early stage, and the potential of Al alloy in the crevice area was higher than that outside the crevice. With increasing corrosion time, under the combined action of Al2O3, SiO2 and metal chloride gradually formed on the surface of Al alloy, the crevice area was reversed into the anode area, with corrosion current density of 3.399 × 10−4 A cm−2, which gradually showed the characteristics of crevice corrosion. This phenomenon suggested that the corrosion products and surface oxides of Al alloy determined the difference of corrosion behavior between the inside and outside crevice. Thus, it is well proved that the WBE is a feasible method to study corrosion behavior of crevice.

Teacher imitation

Not 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.
