Corrosive Wear Behavior of 304 Stainless Steel and Its Variation with Alloyed Oxygen-Active Element Yttrium
Bibliographic record
Abstract
Research was conducted to investigate the sliding wear of Y-free and Y-containing 304 stainless steel in 0.1 mol/1 H2SO4 solution. By the sliding wear test and worn surface analysis (SEM), the authors demonstrated that yttrium considerably improved the resistance of the stainless steel. In order to clarify the mechanism responsible for the improved corrosive wear resistance, yttrium effects on microhardness and polarization behavior of 304 steel were investigated. In particular, the damage and self-healing of passive film was determined using a scratch tester in combination with an electrochemical measurement system. Micro-scratch and micro-indentation tests were also performed with monitoring changes in the electrical contact resistance to evaluate the failure resistance of passive films respectively on Y-free and Y-containing 304 steel specimens. It was demonstrated that yttrium did not significantly influence the mechanical properties of the steel. However, a remarkable improvement in the polarization behavior of 304 steel with the formation of a stronger passive film was observed when a small amount of yttrium was alloyed into the steel. The mechanism responsible for the beneficial effect of yttrium on corrosive wear resistance of the stainless steel is discussed.

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.
