Numerical Simulation of Laser Cladding of Stainless Steel Coatings and Study of the Microstructure and Properties of Multi-Layer Coatings
Bibliographic record
Abstract
In order to study the microstructure and mechanical properties of multilayer Fe-based wear-resistant layer, we establish the finite element numerical model of temperature field of Fe-based stainless steel wear-resistant layer laser-melted on the surface of 42CrMo substrate under different power of heat source, compare the optimal melting process parameters, and carry out the experiments of multilayer laser melting, and observe the surface roughness, microstructure, and micro-hardness of melted area. The results show that the surface quality of the cladding layer is gradually improved with the increase of the number of layers, and the width of the white bright zone in the bonding area and the grain size show a tendency of increasing and then decreasing. The hardness of the top of the cladding layer decreases with the increase of the number of layers, and the average hardness of the bonding zone decreases and then increases with the increase of the number of layers. The hardness of the top of the double-layer cladding is 646 HV, and the hardness value of the bonding zone is 439 HV, which is close to that of the substrate.

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.
