The lifting or flaking of the metal at the surface due to delamination of grain boundaries caused by the pressure of corrosion is
- transgranulation.
- electrolysis.
- exfoliation.
Explanation
Exfoliation is corrosion that progresses along grain boundaries lying parallel to the surface; the bulky corrosion products force the layers apart, lifting and flaking the metal like the leaves of a book. Electrolysis is the electrochemical process itself, and transgranulation is not a corrosion term, so the described appearance is exfoliation.

because exfoliation is the type of corrosion that flaking and generall loss of meterial is observed.

it is the advanced type of intercrangular corrosion
