- Electrochemical methods (current-density-potential-curves):
- Determination of corrosion rates by Tafel extrapolation
- Determination of pittingcorrosion potentials
- Investigation of passivation behavior of high alloyed steels
- Investigation of the sensitization of high alloyed steels (e.g. due to increased temperatures
during welding processes)
-
Impedance spectroskopy for
determination of the charge transfer resistance, electrolyte resistance and double layer capacity or capacities of
surface layers, respectively
- ageing experiments in electrolytes (or other corrosive atmosphere); determination of corrosion speeds by
measurement of sample weight before and after experiments
-
Chemical analyses (EDX,
XPS,
AES,
SIMS),
for determination of corrosion products
- Microscopical investigations (optical microscope, scanning electron microscope) e.g. of fracture
surfaces after stress corrosion cracking or shapes of pittings after pitting corrosion
- Wöhler curves in electrolytes (fatigue corrosion cracking)
