ABSTRACT
The most important cathodic process of metal corrosion is oxygen reduction. This process, however, is a complicated multistep catalytic process. A well known catalytic oxygen activator is the acidic Fe3+/Fe2+ redox system. In the case of rusting iron the Fe2+ ion containing lepidocrocite is the catalytic activator of oxygen. There are many metal complexes capable of oxygen activation. They can help increasing metal corrosion rate.
