Selective corrosion is a type of corrosion which attacks one single element of an alloy and dissolves the element in the alloy structure.
Selective corrosion is a type of corrosion which attacks one single element of an alloy and dissolves the element in the alloy structure. Consequently, the alloy’s structure is weakened.
Examples of selective corrosion:
Dezincification of unstabilised brass causes a weakened, porous copper structure. Also, graphitisation of gray cast iron, leaves behind a brittle graphite skeleton because of the dissolution of iron.
