Corrosion inhibition of carbon steel in artificial seawater by caprylate
Bibliographic record
Abstract
Abstract The corrosion inhibition efficiency of sodium caprylate (SC) in protecting carbon steel (CS) in aqueous 3.5 wt.% NaCl was studied. SC was found to enable good corrosion protection of CS, yielding a maximum corrosion inhibition efficiency of 80 ± 2%. The inhibition efficiency was shown to be directly proportional to the SC surface coverage, characterized by a two‐step adsorption isotherm. The adsorption of SC on CS in the lower SC concentration region was found to follow the Langmuir adsorption isotherm and the first‐order reversible adsorption kinetics. The corresponding Gibbs free energy of SC adsorption was determined to be −23.8 kJ · mol −1 , indicating a highly spontaneous adsorption process. The scanning electron microscopy imaging of the SC‐inhibited CS showed that the surface exhibited good corrosion stability during a 72 h exposure to the test medium.

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.
