Electrochemical aspects of steel corrosion in sea water
Electrochemical determinations of the corrosion parameters of construction steel DIN St 12 and an experimental alloy (2.8 wt.% Cr) were made in synthetic sea water under defined hydrodynamic conditions. The direct method of measuring polarization resistance was used as well as voltammetric and comparative analytical methods.
Experimental results clearly indicated an influence of oxygen on the kinetics of the corrosion process, which could be seen as a change of the control mechanism as the oxygen concentration was varied.
It was shown that the alloying element chromium has a beneficial influence on the corrosion characteristics of the reference steel.
