Research on the corrosion behavior of floating bead low-density cement stone/P110 steel system under different CO <sub>2</sub> pressure
Bibliographic record
Abstract
This study investigates the corrosion state of the floating bead low-density cement stone/P110 steel system in simulated CO 2 -saturated formation water under high and atmospheric CO 2 pressure. Results show that the resistance of the cement stone reaches a maximum value at 28 days and then decreases. The corrosion rate of P110 steel under high pressure is greater than that under atmospheric pressure. There is a certain gap and accumulation of corrosion products between the cement stone and the steel. Additionally, the maximum gap size and corrosion product thickness reach 27.5 and 67.69 μm, respectively. The composition of the corrosion products on the steel surface is mainly FeCO 3 , and the presence of the iron oxides are caused by oxidation. The corrosion products of the cement are also confirmed to be CaCO 3 and a small amount of SiO 2 .

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.
