The potential difference between the alloying elements is the driving force for the preferential attack on the more active element in the alloy. Selective leaching takes place because graphite is cathodic to iron, and gray iron's structure develops an excellent galvanic cell. Graphitic corrosion is favored by relatively mild environments such as:
