| Abstract: | It is an universal phenomenon that open-circuit-potentials of passive metals shifted towards noble direction gradually in natural seawater.Most researchers thought that biofilms gradually formed on the metal surfaces led to the ennoblement.But up to now,no agreement has been reached on both the reason and the mechanism.Generally,there were some opinions as follows:1)the kinetics of cathodic reaction was changed by biofilms;2)the kinetics of anodic reaction was changed by biofilms;3)H_2O_2 exists in biofilms;4)MnO_2 or MnOOH exists in biofilms.In this paper,the ennoblement of the open-circuit-potentials of passive metals was reviewed,taking into account of the reason and the mechanism. |
| Keywords: | natural seawater passive metals biofilms ennoblement of open-circuit-potentials |
