Exploring the Effect of Microstructure and Surface Recombination on Hydrogen Effusion in Zn–Ni‐Coated Martensitic Steels by Advanced Computational Modeling

steel research international, Volume 95, Issue 2, February 2024.
Ultrahigh‐strength steel structures with Zn–Ni coatings show excellent corrosion resistance, but the plating process generates hydrogen, leading to embrittlement. The finite element methods is used to investigate hydrogen concentration during outgassing, considering coating morphology and steel microstructure.
