Development of a Novel Process of Corrosion Rate Estimation of Steel under Stray Current Interference: Q235A Pipe Steel as an Example
Bibliographic record
Abstract
Abstract With the progress of urbanization, stray current corrosion has attracted numerous attention due to its safety threaten to buried metallic pipelines around the urban rail transit system, especially to gas pipelines. A method to monitor the corrosion rate of the gas pipeline is urgently needed in view of the existing indirect method of the long-life reference electrode. In this work, a novel process model of corrosion rate estimation steel under stray current interference was proposed. The electrochemical noise (EN) signal was studied in the frequency domain through combined analysis in terms of fast Fourier transform (FFT) and discrete wavelet transform (DWT). According to the energy value of each crystal, the active energy was proposed as a parameter for the estimation of the corrosion rate under the excitation of stray current. The results showed that there is a negative correlation relationship between corrosion rate rcorr and active energy Ea. Thus, the active crystal energy of EN signal may be applied as the possible monitoring method of corrosion hazard during the stray current corrosion process.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
