Review of Corrosion Influenced by Biofilm on Metallic Materials（Ⅰ）

The effects of microbial fouling biofilm on corrosive behavior of metallic materials are reviewed in this article including 1) formation of microbial fouling biofilm,2) influence of microbial fouling biomfilm on the corrosion of metallic materials,3) influence of microbial fouling biomfilm on the cathodic protection system,4) microorganism in an extreme condition and its related corrosion,5) microbial fouling biofilm causes the deterioration of water in the system of aeroplane and astronauts,6) methods adopted in the research on microbial influenced corrosion(MIC).The MIC damage in practical applications of engineering is so great that further researches shall be conducted and measures shall be taken to prevent it.
