Implication

Simulation study reveals that two-dimensional nanoparticles at concentrations above 3% prevent columnar growth in electrodeposited nickel, highlighting a computational strategy for coating design.

Key Points

To determine how nanoparticle geometries, concentrations, and electrochemical process parameters influence microstructural evolution and columnar growth suppression during nickel electrodeposition.
Simulated polycrystalline nickel electrodeposition using phase-field modeling across varied nanoparticle shapes (spherical and 2D) and concentration levels.
Trained a Random Forest classifier interpreted with Shapley additive explanation (SHAP) analysis to quantify the impact of process and material parameters on microstructure.
Identified gradient coefficient and overpotential as the most dominant variables governing microstructural evolution during electrodeposition.
Demonstrated that 2D nanomaterials (such as MoS2 or graphene) at volume fractions greater than 3% lower interface drag, facilitate smooth interface migration, and suppress columnar grain growth.
