5.6.1 Corrosion Mechanisms

The following Mechanisms of corrosion must be considered in order to characterise the corrosion processes of inorganic materials:

Surface corrosion: Corrosive material loss is even.
Selective corrosion: Easily soluble components are dissolved out of the composite material.
Defect site corrosion: Defects on the surface (impurities, cracks, pause...) provide the attack sites.
Inter-granular corrosion: The corrosive attack proceeds along the grain boundaries.
