| Abstract: | The through one year corrosion potential and polarization resistance for 3 kinds of steels in seabottom sediment of Liaodong
Bay were measured with the “MD” method.
The measurements will have some theoretical and practical values. The theoretical value lies in that the recorded changing
process of the practical corrosion case can be basis for indoor discussion and electrochemical research on the corrosion process.
The practical value lies in that the obtained data can be basis for designing and controlling electrochemical protection systems.
In fact, it is very difficult to measure in situ the corrosion parameters of steels in sea sediment.
