Corrosion Science & Protection

The science of material degradation — galvanic corrosion between dissimilar metals, passive oxide film formation, cathodic protection systems, pitting corrosion initiation, and corrosion rate prediction using electrochemical principles.

Corrosion science studies the electrochemical degradation of metals and alloys when exposed to their environment. From rusting bridges to corroding pipelines, corrosion costs the global economy over $2.5 trillion annually — roughly 3.4% of world GDP. Understanding the mechanisms of oxidation, galvanic coupling, and passivation is essential for designing durable infrastructure.

These simulations let you explore galvanic corrosion between dissimilar metals, visualize passive oxide film growth, design cathodic protection systems, model pitting corrosion initiation, and predict corrosion rates — all with real-time interactive controls and electrochemically accurate models.
