Corrosion Protection of Zinc Alloy Coated Steel By Organic Coatings Pigmented with Strontium Aluminium Polyphosphate
Bibliographic record
Abstract
Strontium aluminium polyphosphate (SAPP) inhibitive pigment formulated into an organic primer for corrosion protection of zinc alloy coated steel in 0.6 M sodium chloride solution was investigated by serial block face imaging using scanning electron microscopy, which provided detailed information on inhibitor releasing, transportation and reaction with zinc alloy substrate. It was found that SAPP contains at least two distinct particle types, one which is strontium rich and another which is aluminium rich. These particles have different release characteristics which are dependent on the local environment. The strontium rich particles release their components faster in near neutral and acidic environment compared with the aluminium rich particles whilst in an alkaline environment the reverse is found. The pH related inhibitor release process and the mixture of the inhibitive pigment with different strontium to aluminium ratios ensure the availability of the inhibitor at both anodic and cathodic locations, which consequently reduced/retarded the corrosion of zinc alloy coated steel.

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.
