Stress Corrosion Cracking Mitigation of 7075-T6 Aluminum Alloy by Thermal Spray Coating
Bibliographic record
Abstract
Abstract High strength Al alloys used in aircraft structures are susceptible to stress corrosion cracking (SCC) in chloride containing environments. This paper outlines the work done to prevent SCC on 7075-T6 aluminum alloys as a function of the surface conditioning and with three different galvanic coatings. Coatings of pure Al, Al-Mg, and Al-Mg-Zn were applied by twin wire arc spraying and evaluated in 3.5 wt. % NaCl solution. Environment assisted cracking tests were performed using a four point loading set up under tensile fluctuating load at low frequency (0.1 Hz). Results indicate that shot peening is beneficial and SCC is inhibited by anodic thermal spray metallic coatings.

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.
