Investigation of Corrosion Properties of a High-phosphorus Ni-P Coating and Corrosion Resistant Alloys in 3.5 Wt.% NaCl Solution
Bibliographic record
Abstract
Abstract In this study, a high-phosphorus Ni-P coating was prepared by electroless deposition method. The characteristics and corrosion property of electroless Ni-P coating were investigated by surface analysis techniques and electrochemical measurements, and compared with L80 steel, corrosion resistant alloys such as 13Cr steel, 316L stainless steel, Inconel and 28Cr steel. The results showed that the high- phosphorus Ni-P coating with amorphous structure contained 88.3 wt.% Ni and 11.7 wt.% P, and improved the corrosion resistance of L80 steel substrate by more than 90 % in Cl-containing medium. The corrosion resistance of Ni-P coating was close to 13Cr steel but lower than Inconel, 316L stainless steel and 28Crsteel. Nevertheless Ni-P coating, similarto Inconel and 28Crsteel, had better resistance to pitting corrosion than 13Cr steel and 316L stainless steel in Cl-containing environment.

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.
