This work presents a numerical uniform corrosion model that predicts the corrosion rate of hot-dip zinc in salt-spray environments by incorporating electrochemical reactions, mass transport via the Nernst–Planck equation, and ionic-strength effects through the Brønsted–Bjerrum relation. The model is calibrated using immersion-test data and extended to account for electrolyte layer growth, droplet deposition, and periodic run-off in salt-spray environments. The calibration establishes a relationship between the porosity of the zinc oxide layer and the rate constant of zinc oxide precipitation. The validated model reproduces the transition from activation- to diffusion-controlled corrosion and captures the experimentally observed corrosion kinetics with an error margin of 20% when electrolyte renewal is included. The results highlight the decisive role of electrolyte dynamics in salt-spray environments and provide a foundation for extending the framework to more complex cyclic corrosion tests.</jats:p>","lang":"eng"}],"type":"journal_article","publication":"npj Materials Degradation","language":[{"iso":"eng"}],"user_id":"114741","project":[{"name":"TRR 285 - Subproject B03","_id":"142"},{"_id":"132","name":"TRR 285 - Project Area B"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"_id":"64250","citation":{"chicago":"Chen, Chin, Martin Hofmann, and Thomas Wallmersperger. “Modeling the Uniform Corrosion Behavior of Zinc in Salt Spray Testing.” <i>Npj Materials Degradation</i>, 2026. <a href=\"https://doi.org/10.1038/s41529-026-00749-0\">https://doi.org/10.1038/s41529-026-00749-0</a>.","ieee":"C.
