Graphite corrosion (spongiosis) in a degenerated nodular graphite iron
| Chemical designation | GJS |
|---|---|
| State | spongiosis |
| Etching | 3 % Nital |
Spongiosis (spongy dissolution) is a form of selective corrosion of cast iron in which the corrosive attack progresses along the graphite-matrix interfaces and dissolves the iron matrix. In this example, the corrosion followed the degenerated graphite pebbles (chunky graphite) in a ferritic matrix.
