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. |
