Abstract
The precise control of tungsten content of electrodeposited nickel–tungsten (NiW) on brass substrate was achieved by applying a well-designed pulse reverse current waveform. A crack-free, uniform and, mirror-like finish surface was obtained by using a novel derivative of propargyl compound, propargyl-oxo-propane-2,3-dihydroxy, as a brightener and grain refiner into the electrodeposition bath. This study indicates that the electrodeposited nickel–tungsten alloys with an optimum tungsten content (32 wt%) possesses outstanding mechanical and, wear performance, also with very low friction of coefficient of 0.2.

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 it
