The Biological Control of Ocean Corrosion

The questions in the research about the ocean corrosion test have been enumerated since half a centuryin this paper. It can be summarized as“3 unequal substitute”. That is: Any artificial medium can't replace the naturalseawater in the corrosion experiment; Any short-time experiment result can't indicate long-term actual sea experimentresult; Any indoor experiment result can't replace the actual sea experiment result. Several viewpoints have been putforward as following. The ocean is an electrolyte system with high biology activity. New idea about the biology controlof oceanic corrosion has been discussed. The corrosion process and contamination process between the metals and themetals on the interface of seawater has been divided three stages. The interplay between their corrosion processes andfouling processes have been discussed respectively and the corrosion has been controlled by attaching biology.
