EIS Investigations of Alkyd and Epoxy Coatings as They Are Chemically Stripped from Steel Panels
Bibliographic record
Abstract
Abstract Electrochemical Impedance Spectroscopy (EIS) has been employed to monitor, and model, real time chemical stripping and de-adhesion of select coatings from steel panels. Instead of the customary salt solution, a water based chemical stripper was used in a custom-built EIS cell. In effect, the stripper was simultaneously used as the electrolyte for the EIS test as well as the modus operandi for stripping the coated panels. Alkyd (3 coats) and epoxy polyamide coatings (2 coats) were compared and contrasted during the chemical stripping process. To examine the influence of pigment types in the coatings, a leafing aluminum alkyd finish in a 3 coat system was compared with an alkyd finish that contained titanium dioxide. The epoxy polyamide coating systems examined contained either non-leafing aluminum or titanium dioxide pigments. The EIS data is discussed in terms of such multivariate factors as the pigment used in the different coating types, the influence of coating chemistry and the unique chemistry of the water based chemical stripper.

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.
