Surmataledion is a digital laboratory focused on surface oxidation and material degradation. Designed for students, professionals, and material-science learners, the app presents oxidation behaviour through clear visuals and structured simulations for easy understanding. The app includes air exposure index, humidity influence scale, surface oxidation spread, sunlight oxidation amplifier, and material resistance score to analyse environmental impact on materials. Learning is enhanced with oxidation scenario quiz, spot the oxidation, oxidation timeline simulator, and app details inside about info app.
