Laser cladding of In-625 alloy for repairing fuel nozzles for gas turbine engines
Bibliographic record
Abstract
Laser cladding provides unique capabilities for repairing damaged components that currently are difficult or even impossible to repair using conventional methods. In this paper, laser cladding of IN-625 alloy was investigated. Testing results reveal that laser-clad IN-625 on wrought IN-625 substrate demonstrates comparable or even substantially improved fatigue life as compared to the IN-625 baseline specimens at the room temperature as well as at elevated temperature. Laser-clad IN-625 also shows slightly improved wear resistance. Therefore, laser cladding of IN-625 is very attractive for repairing various damaged wrought IN-625 components for aerospace gas turbine engines. A case study is also presented in this paper on laser cladding of IN-625 to restore fretted fuel nozzles that currently are difficult to repair using conventional methods.

How this classification was reachedexpand
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.
