Abstract

fetched live from OpenAlex

The corrosion properties of nanocrystalline Co-1.1 and 2.1 wt% P alloys and their annealed alloys as well as nanocrystalline Co were studied in a deaerated 0.1 M sulfuric acid (H2SO4) solution using electrochemical measurements and x-ray photoelectron spectroscopy (XPS) surface analysis. Potentiodynamic polarization testing and impedance measurements revealed that an addition of bulk P content to nanocrystalline Co enhanced the corrosion resistance; however, this enhancement was compromised by the annealing process at 350°C and 800°C. The enhanced corrosion resistance of nanocrystalline Co-P alloys at open-circuit potential was due to the increase of elemental P concentration on the surface that acted to hinder the anodic dissolution kinetics of surface Co following an initial selective dissolution of Co. However, the superior corrosion resistance of Co-P alloys did not last at the high anodic potential region, because of the formation of a nonprotective surface film consisting of mainly hypophosphite and phosphate as well as elemental P showing a pitting corrosion.

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.
