Studies of Corrosion Inhibition Performance of Inorganic Inhibitors for Aluminum Alloy
Bibliographic record
Abstract
In this study, the behavior of sodium silicate (Na2SiO3), manganese sulfate monohydrate (MnSO4·H2O), and ammonium metavanadate (NH4VO3) as corrosion inhibitors for AA6061 aluminum alloy (Al) was investigated. The polarization resistance (Rp) of the Al substrate immersed in 0.1 M NaCl solution was found to be 13 kΩ·cm2. In comparison, the Rp of the Al substrate immersed in 0.1 M NaCl in the presence of Na2SiO3, Na2SiO3/MnSO4·H2O, and Na2SiO3/NH4VO3 inhibitors was found to be 100, 133, and 679 kΩ·cm2, respectively. The best inhibition result was obtained when the mixture of the inhibitors was used with Rp of 722 kΩ·cm2. The maximum percentage of the corroded area calculated from the scanning electron microscopy (SEM) images was found to be 5.7% for Al substrate immersed in 0.1 M NaCl, which decreased to 0.06% when the mixture of the inhibitors was used. The synergetic effects between the three inhibitors were studied, and the results illustrated that the combination of Na2SiO3, MnSO4·H2O, and NH4VO3 provided the best corrosion inhibition properties for Al in aqueous NaCl environments.

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.
